P0412 valve a problem where is valve a located on a 2002 buick rendezvous


This is the electrically driven secondary air injection air pump. Please read all the information at the link before you buy or replace any parts. In most cases the entire air injection pump assembly must be replaced.

Locating cam postioning sensor


Probably not, then. My understanding of the cam position sensor is that it is for sequential multi-port injection, and not for the older style of multi-port injection. In sequential injection, the computer times the injector pulse to coincide with the intake valve opening, and so the need for a camshaft sensor. Before sequential, the injectors were often "bank fired"- all the injectors on one side or bank of the v-6, v-8 were pulsed at the same time. 4 cylinder engines were similar I think, two injectors at a time were pulsed. GM started using SEFI back around 1991, I think, but took a few years before it was widely used.

Its ideling to high getting too much gas how do you turn it down some


Hi.

Since the car is electronic injection and not carb engine you cannot regulate the idle manually. The idle fuel mixture to be injected is automatically determined by the ECU (the car main computer) depending on the inputs delivered from different parts. If the car is idling too high it means that there is a defective part.

Parts that must be tested are the following:

Idle air control valve and solenoid, also called IAC valve. The part is located on top of engine and determines amount of air to be injected when idle.
Vacuum system. The system has many different functions. Test the system for leaks that may result in lean mixture and other collateral problems.
O2 Sensors located in the exhaust system.
Air filter.
MAF sensor and IAT sensor located in the air intake.
Throttle position sensor.

Do also a diagnostic trouble code scanning. If there are codes stored they will help to identify the problem.

Regards.

What is po411 and po445 for 2006 vw jetta/


P0411- Means Secondary Air Injection System Incorrect Flow Detected!
Possible causes - Vacuum hoses damaged.
- Air Pump inoperative.
- Air bypass solenoid circuit open.
- Air bypass solenoid leaking/blocked or stuck open/closed.
- Air diverter valve leaking/blocked or stuck open/closed.
- Air air hoses r Possible solution - Visually inspect vacuum lines for disconnects in the AIR systems and visually inspect for proper vacuum line routing. Repair if necessary.
- Disconnect the air pump hose at the solenoid valve, start the engine and see if there is air being pumped P0445- Means Evaporative Emission Control System Purge Control Valve Circuit Shorted! Possible causes - Damage harness or connectors to the Purge Control Valve
- The valve circuit is open or shorted
- EVAP canister purge volume control solenoid valve may be faulty
P0445 Description The EVAP canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the ECM. The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve. When is the code detected? - An excessively high voltage signal is sent to ECM through the valve

Nissan patrol 2.8l no diesel to the injektors


to test the engine correctly you will need to buy or rent a NOID test light to hook into the injector rail leads to insure the computer is sending a pulse to the injectors if there is no! pulse or signal while cranking the the ECM has gone out . if there is a pulse then check the filters for water contaminents and air locking the secondary pump needs to be checked for pressure and internal failure as well also check the fuel check valve in the main injector pump for sticking shut as well those are the most common failures to that engine also on the main pump check the voltage at the injection pump to insure there is 12 volts with the key on

1998 328i.. Got a 1421 and 1423 code...not sure where to start...


1997 BMW 328I 2.8L Customer Concern: MIL is on with trouble codes P1421 and P1423, for incorrect secondary airflow on both cylinder banks. Tests/Procedures: 1. Perform a functional test of the Air Injection Reaction (AIR) system. Tee a vacuum gauge into the vacuum hose attached to the diverter valve, located on the cylinder head towards the front of the engine.

2. Allow the vehicle to sit over night. Start the engine (cold) while monitoring the amount of vacuum on the gauge at startup. At temperatures from -10 to 40 degrees Celsius, there should be at least 17 inches of vacuum. At the same time, the AIR pump should run and pump a large volume of air into the exhaust. Potential Causes: A.I.R. Pump
Air Pump Relay
Restricted Cylinder Head
Diverter Valve
Tech Tips: These codes are related to a problem detected in the Secondary Air Injection system. Scan tools with BMW software include a feature to command the AIR pump on and off. The pattern failures for these codes are the AIR pumps due to leaks in the diverter valve and moisture or condensation in the AIR pump.

Possible fix but not all items. Just areas to look at:
Confirmed Fix - A.I.R. Pump - A.I.R. Diverter - A.I.R. Pump, Air Injection Reaction Diverter (AIRD) Valve - Air Injection Reaction Diverter (AIRD) Valve - Check Valve, Secondary Air Pump - Diverter Valve Vacuum Lines

Code p0412 , what is the fix? 1995 mitsubishi eclipse with a dodge avenger 2.0 engine.


P0412 Pulsed secondary air injection solenoid circuit, with seeing it and what it is doing i would guess replace the secondary air injection solenoid control valve.

My 2005 chevy trail blazer has code p0410 and i dont know what needs to be replaced provide that i know that it means secondary air injection system but i need to know the part that needs replacement


check the air pump on your trailblazer, make sure its clean inside and the hoses are properly fastened. also check to make sure it works properly by listening for it when you start the vehicle. if the air pump is working correctly, replace the position 1 o2 sensor meaning the sensor on the exhaust manifold. the air pump is located under the vehicle, inside the frame rail on the drivers side in front of the transfer case crossmember with 2 hoses connected to it.
