SOURCE: 1985 mercedes-benz 190D, 2.2, automatic, are there

hello I'am a mercedes tech. when I service a deisel engine I never put syn. oil in a diesel because it is thin and I don't care what you do all disels leak oil because they have very high compression. I use 20/50 valvoline. As far as your fuel inj, cleaner we use techroline from chevron and when I service the fuel filters I add a filter full of transmission fluid( atf dex. merc.) it helps unclog and properly lube your mechanical fuel inj. I fill the big metal canister 1/2 to 3/4 full of a.t.f.. Also check your inj. return hoses they often leak. they are the black hoses running from the fuel rack to the injecter. replace if oily. If you have miner seap of engine oil do not worry too much about it that is why your car has that huge incapsulation panal underneath the engine and trans. If you have a good leak I would pressure wash the engine and inspect it for leaks. If you can,t find the leak add oil dye and inspect with blacklight. Just moniter the oil level. There is a spec. as far acceptable amount of oil consumption. I believe it is something like 1 quart for every 1,000 miles. You can take it to m.b. shop and have it set up for an oil consumption test if you are not sure. I hope this might help you with your questions.

SOURCE: How much should it cost to fix/re-gas the A/c?

anywhere from $10.00 - $1200.00 depending on what all it needs and who's doing the work. I wish I could be more specific, but if you just need to put in some gas, you can get that for about $10 a can, but if you need to replace the compresor and all othe required parts it can get pricy for the parts let alone labor- heck the $1200.00 may even be a bit low. Don't mean to scare you, but you have to remember that you are driving a high end luxuary car, and they cost $$ to maintain.Ask me how I know :-)

I would like to know what the code PO455 on a 2007 Mitsubishi Endeavor means.


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
help.jpg What does this mean? Tech notes
The P0455 it's a very common code, because the code is set if the gas cap is loose or missing. Start by tighten the gas cap and clearing the code. In most cases the code can be clear by disconnecting the car battery for about 30 minutes.
help.jpg What does this mean? When is the code detected?
Evaporative Emission System (EVAP) control system has a very large leak such as fuel filler cap fell off, EVAP control system does not operate properly.
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vapors
P0455 Mitsubishi 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.

Code po455 2004 chrysler sebring 2.4l sohc G vin code


The code is for a large leak in the fuel tank or evap system.

Some possible cause are - a leaking fuel tank, gas cap, hoses to and from the vapor canister and engine, and a faulty canister.
It's possible a valve is stuck open and allowing the engine to pull fumes in when the system is supposed to be closed, but if this were the case the computer should also set a code for that valve.

Here is the definition.

P0455 CHRYSLER Description The Evaporative emissions (EVAP) system is design to prevent the escape of fuel vapors from the fuel system. Leaks in the system, ca allow vapors to escape into the atmosphere. The leak detection system tests for EVAP system leaks and blockage.


During the self-diagnostics, the Powertrain Control Module (PCM) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM then uses the LDP to seal the vent valve and pump air into the system to pressurize it. If a leak is present, the PCM will continue pumping the LDP to replace the air that leaks out. The PCM determines the size of the leak based on how fast/long it must pump the LDP as it tries to maintain pressure in the system.

Code P0455 evaporative emission system leak ( large leak) 2002 Mitsubishi diamante


Could be a number of things...rusty filler neck, or a bad "vent solenoid." These are more common. The evap system closes once you are driving it to send fuel vapors to a charcoal canister, and if it can't due to a leak, your check engine light will go on.

Check engine light is on for emission evaporator failure-large


P0455 - EVAP Control System Leak Detected (No Purge Flow or Large Leak) The PCM monitors the complete EVAP control system for no purge flow, the presence of a large fuel vapor leak or multiple small fuel vapor leaks. The system failure occurs when no purge flow (attributed to fuel vapor blockages or restrictions), a large fuel vapor leak or multiple fuel vapor leaks are detected by the EVAP running loss monitor test with the engine running (but not at idle).
  • After-market EVAP hardware (such as fuel filler cap) non-conforming to required specifications
  • Disconnected or cracked fuel EVAP canister tube, EVAP canister purge outlet tube or EVAP return tube
  • EVAP canister purge valve stuck closed
  • Damaged EVAP canister
  • Damaged or missing fuel filler cap
  • Insufficient fuel filler cap installation
  • Loose fuel vapor hose/tube connections to EVAP system components
  • Blockages or restrictions in fuel vapor hoses/tubes (items also listed under disconnections or cracks)
  • Fuel vapor control valve tube assembly or fuel vapor vent valve assembly blocked
  • Canister vent (CV) solenoid stuck open
  • Mechanically inoperative fuel tank pressure (FTP) sensor
Check for audible vacuum noise or significant fuel odor in the engine compartment or near the EVAP canister and fuel tank. ----------------------------------------------------------------------------- HX43 DTC P0457: CHECK FOR MISSING OR LEAKING FUEL FILLER CAP
  • Check for missing fuel filler cap.
  • Check for loose fuel filler cap.
  • Check for possible cross-thread fuel filler cap condition.
Is a fault present concerning the proper installation of the fuel filler cap? Yes No REPLACE cross-threaded or damaged fuel filler cap. RECONNECT and TIGHTEN the fuel filler cap only one eighth turn so that the cap initially clicks by sound or touch. CLEAR Continuous Memory DTCs. COMPLETE an Evaporative Emission Running Loss Monitor Repair Verification Drive Cycle (refer to Section 2 , Drive Cycles). RERUN Quick Test . If DTC P0455 or P0457 is present, Go to HX44 . CLEAR Continuous Memory DTCs. COMPLETE an Evaporative Emission Running Loss Monitor Repair Verification Drive Cycle (refer to Section 2 , Drive Cycles). RERUN Quick Test .

For DTC P0455 still present: Go to HX44 .

Otherwise, INFORM the vehicle owner that it is important and necessary to immediately install the fuel filler cap after every refueling event. HX44 DTC P0455: VISUAL INSPECTION FOR SUBSTANTIAL EVAPORATIVE EMISSION SYSTEM LEAKS
  • Check for missing fuel filler cap. If the cap is loose DO NOT DISTURB EVAP system.
  • Verify that both the input port vacuum hose and EVAP return tube are attached to the EVAP canister purge valve. Note: If the EVAP canister-CV solenoid assembly is not accessible during this pinpoint test step, GO to Evaporative Emissions, Section 303-13 in the Workshop Manual for removal and installation instructions.
  • Verify that the CV solenoid is properly seated on the EVAP canister (if possible).
  • Visually inspect for disconnected or cracked fuel vapor hoses/tubes between the intake manifold, the EVAP canister purge valve, the EVAP canister, the fuel vapor vent valve assembly and if applicable the fuel vapor control valve tube assembly.
  • Check for damage to the fuel filler pipe and the fuel tank.
Is a fault indicated? Yes No CONNECT or REPLACE fuel vapor hoses/tubes as required. REPLACE damaged EVAP system components (fuel filler pipe, fuel vapor vent valve assembly, fuel vapor control valve tube assembly, EVAP canister purge valve, FTP sensor and EVAP canister-CV solenoid assembly) as necessary. REFER to Evaporative Emissions, Section 303-13 in the Workshop Manual for removal and installation instructions. GO to HX45 . GO to HX45 . HX45 DTC P1443 and P0455: CHECK FOR EVAPORATIVE EMISSION SYSTEM LEAKS
    Note: When checking for leaks or blockages in the EVAP system, energize (close) the canister vent (CV) solenoid through the scan tool for a maximum of nine minutes per pinpoint test step. Then de-energize the CV solenoid prior to performing the subsequent pinpoint test step. This is done to assure proper closing of the solenoid.
  • Disconnect and plug the EVAP return tube (EVAP canister purge valve to intake manifold) at the intake manifold vacuum source.
  • Connect scan tool.
  • Key on, engine off.
  • Access VPWR PID. If the voltage is not 12 volts or greater, GO to HX61 .
  • Locate evaporative test port [marked EVAPORATIVE SERVICE PORT DO NOT USE UNREGULATED PRESSURE ABOVE 6.89 kPa (1 PSI)] near EVAP canister purge valve or EVAP canister.
  • If vehicle is not equipped with the evaporative test port, GO to HX50 .
  • Install the Rotunda Evaporative Emission System Leak Tester 310-F007 (134-00056) or equivalent at the evaporative test port.
  • Close CV solenoid by accessing Output Test Mode on the scan tool.
  • Select ALL OFF mode and push START button.
  • Regulate the nitrogen or argon gas pressure on the tester to 3.48 kPa (14 in-H 2 O).
  • Follow the instructions that come with the EVAP System Leak Tester and pressurize the EVAP system.
  • Perform the EVAP system leak test.
Does the pressure on the EVAP system stay above 1.99 kPa (8 in-H 2 O) and pass the leak test? Yes No GO to HX46 . REMOVE the EVAP System Leak Tester from the evaporative test port and REINSTALL the test port cap. GO to HX50 .
