SOURCE: Troubleshooting code PO753 ECM or PCM.

It is more likely the solenoid, the PCM is very seldom the problem, about 3% of the time to be exact.

SOURCE: im getting a P0441 EVAP emission control system

Here is what I could find for your code error as potential causes:
After market parts and accessories nonconforming to the EVAP system specifications.
Damaged, missing or improperly installed fuel filler cap.
Blockage in fuel vapor hoses/tubes (EVAP canister tube, EVAP canister purge outlet tube or EVAP return tube) in EVAP system.
Disconnected or cracked fuel vapor hoses/tubes in EVAP system.
EVAP canister purge valve stuck closed.
Canister vent (CV) solenoid stuck open.
Fuel tank pressure (FTP) sensor malfunction.
EVAP canister leaking.
Fuel vapor control valve tube assembly blocked.
Fuel vapor vent valve assembly blocked.

Obviously the gas cap would be the easiest and cheapest thing to fix.  Just make sure it is put on correctly and tight.  If it is not that, I would have to suggest to take it to a mechanic because the other problems on that list are not really DIY material.  Hopefully it is the gas cap and you can take care of it yourself.  Good luck.

SOURCE: 2002 DODGE NEON 2.0 ENG. A/T WHERE IS THE TCC

the tcc solenoids are in the transmission,but the computer sees that the torque converter didn't lock up,so it blames the solenoid in charge of doing that,
but you will probably find the converter is going bad,a tranny shop will be able to verify which is not working.

Hi, these are taken from the data sheets

P1523 - electronic throttle system (ETS) - throttle valve sticking - probable cause = mechanical fault, ECM

P0204 - injector 4 - circuit malfunction - probable cause = wiring, injector, ECM

P0206 - injector 6 - circuit malfunction - probable cause = wiring, injector, ECM

hope that helps

2003 chevy silverado injector 2 fuse blows when ignition is turned on


You ohmed them but did you check them for continuity to GROUND, to find out if one of them is grounded out ! They normally ground to ecm/pcm not to eng. so check them for short to grd with wire harness unplugged from all injectors and check 1 at a time, If they all show open...no ground then check your power should be pink for chafing or bare short to ground. this will be on Bank 2 you are checking which is the Head that setsfarthest back to firewall. Bank 1 is Head farthest to front towards Radiator.

Did you clear the codes? Car may still be in limp mode...
Also the 303 is odd. Are the sparks good on #3? May have an issue with coil or ignition module.

1998 ranger 2.5 manual enging miss


ck for leak at intake. if no leak pcm/ecm may be sending fire command to slow to # 1 . the fuel injector is always hot the ecm sends a ground to the injector. even new parts can be bad ck inj, with ohm meter resistance should be the same between each inj. im not sure of the specifications but they should read the same my jimmy specs are 1.9-2.1 any other reading is bad . no resistance or lower or higher readings my injector would be bad. 140 is good reading, timing can be off a little and still run but rough like a miss. a code wont set most misfires will set a dtc or flash the engine light to let you know damage to cat system is happening , to much fuel a system rich,to little a lean. a bad mass airflow meter can also cause a misfiring or rough idle ck with scanner if dirty clean with brake cleaner first before replacing . hope this helps some let me know how it goes.

Lost inj. pulse need to know where the ecm gets crank position from. if from dist.how does it locate #1 1985 crovette


Lost injector pulse. First injector power is supplied by (IGN+) or fues block ,The injector are multi-potr not individual they are fired together,not individually, Now if you lost injection pulse youll need to inspect the Distributor,the pick up is highly suspectable to terminal corrosion, it corrodes easily,so be ready to replace the pick up with a module, (this is spark I know we are on Injector), Do you have spark, then leave this alone, Test injector pulse not at the injector because again its bank fire or group fired You ll need to test thes the connector harness connector,of the injectors.As long as there is spark you should have injector pulse from the injector sub harness connector make your way to the ECM , The ECM controls the energizing of the injector with a transitor or quad driver,they are synchronized to primary ignition . Here a solution if no spark correct for spark. Its either a Distributor pick up failure with ICM module.Do this only is you have no spark.If you have spark and no Injector ,replace ECM

I would like to know what the following codes represent for my 2002 jaguar x-type 3.0 Codes are P174, P175, P1111


P1110 Intake Air Temperature Sensor Signal (Dynamic Chamber) Circuit
The other DTC refer to mixture issues.

From http://www.bluejag.co.uk

Fault Code:- P0174 Indicates a Power-train fault
The fault is generally due to a problem in the Emission Management (Fuel or Air) area
Fault Description: Bank 2 combustion too lean
Action of ECM:- ECM Default: - Bank 2 catalyst warm-up ignition ****** inhibited - Bank 2 closed loop fuel metering inhibited - Canister purge inhibited - Maximum engine speed reduced
Possible Fault:-
Engine misfire Air intake leak between MAF Sensor and throttle Fuel filter / system restriction Fuel injector restriction Low fuel pump output HO2 Sensor(s) (2/1, 2/2) harness wiring condition fault Exhaust leak (before catalyst) ECM receiving incorrect signal from one or more of the following components: ECT Sensor, MAF Sensor, IAT Sensor, TP Sensor

once again from http://www.bluejag.co.uk

Fault Code:- P0175 Indicates a Power-train fault
The fault is generally due to a problem in the Emission Management (Fuel or Air) area
Fault Description: Bank 2 combustion too rich

Action of ECM:- ECM Default: - Bank 2 catalyst warm-up ignition ****** inhibited - Bank 2 closed loop fuel metering inhibited - Canister purge inhibited - Maximum engine speed reduced


After clearing the DTC, complete the Start engine and bring to normal operating temperature > 82 °C (180 °F) Idle for 10 minutes

Check for a reoccurrence of fault DTC.

Possible Fault:- Restricted air filter Leaking fuel injector(s) ECM receiving incorrect signal from one or more of the following components: ECT Sensor, MAF Sensor, IAT Sensor, TP Sensor

Injectors 1, 3, and 5 not firing.


With that many injectors not firing, I would look at the ecm or engine computer seriously.

I had a 1990 Cadillac Deville that after changing all 8 inj. and an egr valve, and other parts... it finally turned out to be the ecm not firing one of the injectors, causing a miss on an OBD-I automobile.

You could try to replace the injectors that are on 1,3, and 5, but it if that doesn't work, it's probably the ecm, in my opinion.

Dead cylinders 2003 sebring


it sounds like you may have the wires on the wrong coil. It should be #1 on the #4 coil, and the #3 wire on the #2 coil. you probably have them backwards so 1 and 3 are firing on the exhaust stroke.
the firing order is 1-3-4-2.
they should be hooked like this.
