  • EVAP Purge Solenoid Operation
  • Intermittent LDP Monitor Failure
  • Evaporative Emission Leak Detection

WHAT ENGINE DIAGRAMS I HAVE IS BELOW WITH DEFINITIONS
  • dak408_24.gif
On 4.0L 6 cylinder engines, a molded vacuum tube connects manifold vacuum to top of cylinder head (valve) cover at dash panel end. The vacuum fitting contains a fixed orifice of a calibrated size. It meters the amount of crankcase vapors drawn out of the engine.

On 2.5L 4 cylinder engines, a fitting on drivers side of cylinder head (valve) cover contains the metered orifice. It is connected to manifold vacuum.

A fresh air supply hose from the air cleaner is connected to front of cylinder head cover on 4.0L engines. It is connected to rear of cover on 2.5L engines.

When the engine is operating, fresh air enters the engine and mixes with crankcase vapors. Manifold vacuum draws the vapor/air mixture through the fixed orifice and into the intake manifold. The vapors are then consumed during combustion.

EVAP/PURGE SOLENOID
The duty cycle EVAP canister purge solenoid (DCP) regulates the rate of vapor flow from the EVAP canister to the intake manifold. The Powertrain Control Module (PCM) operates the solenoid.

During the cold start warm-up period and the hot start time delay, the PCM does not energize the solenoid. When de-energized, no vapors are purged. The PCM de-energizes the solenoid during open loop operation.

The engine enters closed loop operation after it reaches a specified temperature and the time delay ends. During closed loop operation, the PCM cycles (energizes and de-energizes) the solenoid 5 or 10 times per second, depending upon operating conditions. The PCM varies the vapor flow rate by changing solenoid pulse width. Pulse width is the amount of time that the solenoid is energized. The PCM adjusts solenoid pulse width based on engine operating condition.

FUEL FILLER CAP
The plastic fuel tank filler tube cap is threaded onto the end of the fuel fill tube Certain models are equipped with a 1/4 turn cap.

The loss of any fuel or vapor out of fuel filler tube is prevented by the use of a pressure-vacuum fuel fill cap. Relief valves inside the cap will release fuel tank pressure at predetermined pressures. Fuel tank vacuum will also be released at predetermined values. This cap must be replaced by a similar unit if replacement is necessary This is in order for the system to remain effective.

CAUTION: Remove fill cap before servicing any fuel system component to relieve tank pressure. If equipped with a California emissions package and a Leak Detection Pump (LDP) , the cap must be tightened securely. If cap is left loose, a Diagnostic Trouble Code (DTC) may be set.

LEAK DETECTION PUMP
The Leak Detection Pump (LDP) is used only with certain emission packages

The LDP is a device used to detect a leak in the evaporative system.

The pump contains a 3 port solenoid, a pump that contains a switch, a spring loaded canister vent valve seal, 2 check valves and a spring/diaphragm.

Immediately after a cold start, engine temperature between 40 °F and 86 °F , the 3 port solenoid is briefly energized. This initializes the pump by drawing air into the pump cavity and also closes the vent seal. During non-test test conditions, the vent seal is held open by the pump diaphragm assembly which pushes it open at the full travel position. The vent seal will remain closed while the pump is cycling. This is due to the operation of the 3 port solenoid which prevents the diaphragm assembly from reaching full travel. After the brief initialization period, the solenoid is de-energized, allowing atmospheric pressure to enter the pump cavity. This permits the spring to drive the diaphragm which forces air out of the pump cavity and into the vent system. When the solenoid is energized and de-energized, the cycle is repeated creating flow in typical diaphragm pump fashion. The pump is controlled in 2 modes:

Pump Mode: The pump is cycled at a fixed rate to achieve a rapid pressure build in order to shorten the overall test time.

Test Mode: The Solenoid Is Energized With A Fixed Duration Pulse. Subsequent fixed pulses occur when the diaphragm reaches the switch closure point.

The spring in the pump is set so that the system will achieve an equalized pressure of about 7.5 inches of water.

When the pump starts, the cycle rate is quite high. As the system becomes pressurized pump rate drops. If there is no leak the pump will quit. If there is a leak, the test is terminated at the end of the test mode.

If there is no leak, the purge monitor is run. If the cycle rate increases due to the flow through the purge system, the test is passed and the diagnostic is complete.

The canister vent valve will unseal the system after completion of the test sequence as the pump diaphragm assembly moves to the full travel position.

VACUUM LINES
A vacuum schematic for emission related items can be found on the VECI label. Refer to Vehicle Emission Control Information (VECI) Label for label location

dak408_25.gif
VAPOR CANISTER
The evaporative (EVAP) canister is located in the engine compartment on the left inner fender.

A maintenance free, EVAP canister is used on all vehicles. The EVAP canister is filled with granules of an activated carbon mixture. Fuel vapors entering the EVAP canister are absorbed by the charcoal granules.

Fuel tank pressure vents into the EVAP canister. Fuel vapors are temporarily held in the canister until they can be drawn into the intake manifold. The duty cycle EVAP canister purge solenoid allows the EVAP canister to be purged at predetermined times and at certain engine operating conditions.

ONE WAY TO CLEAR ENGINE CODES WITH OUT HAVING A DIAGNOSTIC COMPUTER IS UN PLUG THE BATTERY AND LEAVE IT SIT FOR ROUGHLY 20 MINUTE AND REHOOK UP THIS MIGHT CLEAR THE CODES WITH OUT A COMPUTER.. BUT IF THE PROBLEM ISN'T FIXED THE CODES WILL SHOW AGAIN..


HOPE THIS HELPS

There is a purge solenoid for the EVAP system and it is item no.# 1 shown in the diagram below. You have to follow the purge valve vacumn hose to find the charcoal cannister if you need to inspect.

tdisline_101.jpg
I have included a description of the EVAP system for your understanding.

EVAPORATIVE EMISSION (EVAP) CONTROL SYSTEM
The EVAP and on-board refueling vapor recovery (ORVR) system consists of a fill vent valve, fuel shut-off valve, fuel cut (roll-over) valve, fuel liquid/vapor separator, EVAP canister, EVAP canister purge solenoid valve, EVAP canister close valve, vacuum relief filler cap, and connecting lines and hoses. ORVR system is designed to prevent the release of fuel vapors during refueling. During refueling, as fuel enters the fuel tank, a vacuum is created in filler pipe, drawing air into the filler pipe and tank. Fuel vapor in fuel tank is then forced to the EVAP canister via the fill vent valve and the fuel liquid/vapor separator. A fuel tank pressure sensor is used for detecting EVAP system leaks by comparing pressures inside and outside of fuel tank.

EVAP Canister Purge Solenoid Valve
Fuel vapors are vented into the EVAP canister during refueling and when ignition is off. When engine is at normal operating temperature and engine speed is greater than idle, a thermovalve opens and allows vacuum to open the purge control valve. Canister vapors are then drawn into the intake manifold for burning during combustion. The purge control valve is kept closed during idle and engine warm-up to reduce HC and CO emissions.

P2187 code on 2006 sonata v6


(adsbygoogle = window.adsbygoogle '' []).push({});

P2187 System Too Lean at Idle (Bank 1) DTC
OBD-II Trouble Code Technical Description
Article byDon BowmanASE Certified Automotive TechSystem Too Lean at Idle (Bank 1)
What does that mean?
This diagnostic trouble code (DTC) is a generic powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may be slightly different depending on the model.
(adsbygoogle = window.adsbygoogle '' []).push({});
This is an ambiguous code in of itself. It can be a tough code to crack without a diagnostic strategy. During the last two starts, the engine management computer has recognized a problem with the fuel mixture at an idle.
It appears that the fuel mixture is too lean (too much air and not enough fuel) at an idle. If you have a 4 cylinder engine the "Bank 1" is meaningless, however, if you have a 6 or 8 cylinder engine, Bank 1 will be on the side with the number one cylinder. Code P2189 is the same code but for Bank #2.
There is a laundry list of components that could cause this scenario. For the most part the diagnostic procedure is not difficult -- just time consuming, unless it is one of the first items checked. The strategy dictates that the driveability problems are observed and noted, then start with the most commonly found problems and progress from there.
Symptoms
With the wide range of possibilities, the problems listed may and may not be present. But, here is where it is important to pay particular attention to the symptoms observed and make a note as to what and when symptoms appear for diagnostic strategy.
Vehicle has a miss at an idle
Hard to start, especially when hot
Very irregular idle
Additional codes to pinpoint cause of original P2187 code
Whistling noises
Lower turbo boost numbers
Fuel smell
Potential Causes of P2187 DTC
Faulty O2 sensor (front)
Faulty gas cap seal
Leaky or loose oil filler cap
Air leaking into the intake manifold downstream from the Mass Airflow sensor due to the manifold itself, vacuum hoses off or cracked, leak MAP sensor, Leak at turbo bypass or it's stuck open, power brake booster hose, or a leak in the EVAP system hoses.
Faulty MAP sensor
EVAP canister purge valve
Fuel injector leak
Fuel pressure regulator faulty
Leaks in the exhaust system
Faulty variable camshaft timing
Faulty ECM (engine management computer)
Faulty O2 preheater (front)
Clogged fuel filter
Fuel pump wearing out and producing low pressure.
Faulty mass air flow sensor
Diagnostic / Repair Steps
Your strategy for locating this problem begins with a test drive and observation of any symptoms. The next step is to use a code scanner (available at any auto parts store) and pulling any additional codes.
The computer has set a code P2187 stating that the fuel mixture is lean at an idle. This is the main code, however, any component malfunctioning within this loop that has the potential to cause a lean mixture will also be set in code.
If the test drive doesn't produce any symptoms it is possible that it is not a real code. In other words, the fuel mixture is not lean and that the computer or oxygen sensor is responsible for setting the code.
Every vehicle has a minimum of two oxygen sensors -- one in front of the catalytic converter and one after the converter. These sensors signal the amount of free oxygen left in the exhaust after ignition, which determines the fuel ratio. The front sensor is primarily responsible for the mixture, the second sensor behind the exhaust is used for comparison to the front sensor to determine if the converter is working properly.
If a rough idle is present or one of the other symptoms, begin the process with the most likely cause first. Either unmetered air is entering the intake manifold or there is a lack of fuel pressure:
Check the fuel cap for cracks and sealing and function
Lift the hood and make sure the oil filler cap is tight
If additional codes were present begin with inspecting them first
Look for air leaks starting at the mass airflow sensor. Check the hose or connection between the sensor and the intake manifold all the way to the manifold for cracks or loose connections. Check all vacuum hoses carefully attached to the intake manifold, to include the one to the vacuum brake booster. Check the hose to the MAP sensor and all hoses to the turbo if so equipped.
With the engine running, using a can of carburetor cleaner and spray a small mist around the base of the intake manifold and where the two halves meet if it is a two piece. Spray around the base of the EGR for leaks into the manifold. The rpm will increase if a leak is located.
Check the PCV valve and hose for leaks.
Inspect the fuel injectors for external fuel leaks
Inspect the fuel pressure regulator by pulling off the vacuum hose and shaking it to see if fuel is present. If so replace it.
Shut the engine down and install a fuel pressure tester on the schrader valve on the fuel supply rail to the injectors. Start the engine and note the fuel pressure at an idle and once again at 2500 rpm. Compare these figures with the desired fuel pressure found online for your vehicle. If out of range in volume or pressure replace the pump or filter.
The remainder of components need to be inspected by a service facility that has a Tech 2 scanner and programmer.

How do I resolve diagnostic code P0455 on my 2005 Chevrolet Tahoe?


Here is the definition and possible causes.

Possible causes - Missing or loose fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- EVAP canister or fuel tank leaks
- EVAP system hose leaking
- Fuel tank leaking
P0455 CHEVROLET Description This diagnosis detects leaks in the Evaporative Emission System (EVAP) purge line using engine intake manifold vacuum. If pressure does not increase, the Engine Control Module (ECM) will check for leaks in the line between the fuel tank and EVAP canister purge volume control solenoid valve under the following vacuum test condition.


The vacuum cut valve bypass valve is opened to clear the line between the fuel tank and the EVAP canister purge volume control solenoid valve. The EVAP canister vent control valve will then be closed to shut the EVAP purge line off. The EVAP canister purge volume control solenoid valve is opened to depressurize the EVAP purge line using intake manifold vacuum. After this depressurization is implemented, the EVAP canister purge volume control solenoid valve will be closed.

Check engine light ...code came up p0455 i have a 06 mazda 3 2.3


This indicates a fuel vapor leak or lack of purge flow in the EVAP control system. It means a large leak has been detected. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

Symptoms: You likely won't notice any drivability problems.

Causes: A code p0455 most likely means one or more of the following has happened:
* A loose or improperly affixed gas cap
* A non-conforming gas cap (i.e. not factory/original brand)
* Other leak or damaged piece in EVAP system

Possible Solutions: With a p0455, the most common repair is to:
* Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
* Otherwise, replace the gas cap, and/or
* Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary


Hope this helps (remember to rate thsi answer).
