2 months ago "check fuel cap" came on...replaced cap...cleared the code. All was fine for a couple of weeks. Then "service engine soon" light came on...po455 came up, so i cleared the code..all was fine... then the vehicle died on the way to work...checked the codes, and now i get p2104, p2106, 2110, & p2135?
(so i cleared the code..all was fine.) No it wasn't ,you don't just clear code's without doing the diagnostic's for that code . It's just a matter of time ,when the PCM/ECM - engine computer runs that test again, that light will come back on. P0455 is a large leak in the evaporative emission system .Sorry dude but you don't stand a snow ball's chance in guam of fixing this .
Do you know what electronic throttle control is ?
P2135 - ETC Throttle Position (TP) Sensor A/B Voltage Correlation
Description:
The powertrain control module (PCM) flagged a fault indicating that TP1 and TP2 disagree, or that TP1 should not be in the present position given the position of TP2 unless a concern is present.
Possible Causes:
Diagnostic Aids:
Compare the TP1 and TP2 PID values for a full sweep and correlation. Refer to the chart in pinpoint test DV. GO to Pinpoint Test DV .
Compare TP1 and TP2 PID values to the typical reference values in Section 6 .

P2110 - Throttle Actuator Control (TAC) System - Forced Limited RPM
Description:
The TAC system is in the failure mode effects management (FMEM) mode of forced limited RPM.
Possible Causes:
Diagnostic Aids:
This DTC indicates only that the FMEM condition exists, and can be set in combination with DTCs P2100, P2101, or P2107, meaning the electronic throttle body (ETB) faults should be diagnosed first.

Do yourself a favor an take it to a qualified repair shop.
P0455 - Evaporative Emission (EVAP) Control System Leak Detected (No Purge Flow or Large Leak)
Description: The powertrain control module (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. 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).
Possible Causes: After market EVAP hardware (such as the 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 the EVAP system components.
Blockages or restrictions in the 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.
Diagnostic Aids: Check for audible vacuum noise or significant fuel odor in the engine compartment or near the EVAP canister and fuel tank.

Code p 2104 refers to throttle position actuator (TAC) system --forced idle mode===causes wiring ---TAC motor --APP (accelerator position sensor)---ECM
code p 2106 is the same TAC-- forced limited power mode ===causes --same as 2014
code p 2110 refers to TAC same as 2104 plus it refers to heated oxygen sensor (HO2S) 1 bank 1 implausible signal==causes wiring ---short to positive --short to ground ---HO2S ---ECM
code p 2135 refers to accelerator pedal position (APP) sensor/ switch A/B ---voltage correlation====causes wiring---APP sensor/switch
it also refers to electronic throttle unit , throttle position (TP) sensor/switch--implausible signal====causes wiring --TP sensor /switch
remember---clearing a code with out fixing the fault is not a fix for the fault
SOURCE: Service Engine soon light, codes P0301 and P0171, replace plugs
Hi,, Well the service engine light comes on when your car needs to be tuned up, this happens when the timing belt needs changing or nearing its life span. Basically it involves changing the belt (optionally >) engine oil, transmission fluid, radiator coolant, fuel injection and throttle body servicing, changing gas filter, air filter etc. Its to prevent damages to your car. After its serviced the mechanic will need to clear all error codes and reset the cars computer. Clearing the error codes is done with a diagnostic tool, to reset the cars computer , remove the negative battery pole and press the brak as far as it will go, wait 60 second release and reconnect the battery pole. Some vehicles may need to be caliberated if it has an electronic throttle body system
SOURCE: why does my '02 mountaineer keep dying on me?
I'd be looking at the idle air control valve on side of throttle body. It regulates idle under load conditions such as when turning, AC on, heater etc, brakes applied etc, & steps idle up to maintain proper idle.When this goes faulty it lots of times doesn't send a code. You may get away with just pulling it off and cleaning plunger & port it comes out of with throttle body spray cleaner,It's worth a try before you replace.

without a fault code its impossible to diagnose. try pep boys or aamco or auto zone they will pull the code for you, usually for free. The code will relate to a sensor or area to be fixed. This will save you money and needless parts . post the code or codes so we can help
SOURCE: Check Engine Light Problem
Codes that tell you your engine is running lean can be caused by a number of things. First thing to do (and cheapest) is to get some fuel injector cleaner and run it for awhile. Dirty injectors can cause these codes. I recommend lucas brand myself but there are several different cleaners to choose from. The second thing is checking your vacuum lines. If there is a leak it can cause the engine to **** in too much air and cause the codes. Anything beyond that gets into alot of mechanical work and should be done by a certified technician
SOURCE: 2006 mountaineer check engine light on
look closely at the cap to make sure the rubber seal isn't damaged, have the cap vacuum checked. if everything is ok with the cap, scan for what the check engine light code is. if it is a large evap system leak, the system may think the cap is off because it cannot build up any pressure in the system.
