SES CODES: 2002 Chrysler Concorde Limited Addition
Hello there.
MY 2002 C.C. pulled two SES light codes... p0175/p0300 I have had the O2 sensor replaced and one day the light came again. Any help?? Thanks, G |
Are these the codes that came when the light came on again? Can't be sure with the chronology of your post.
The P0175 in an indication that the system believes that bank 2 is running rich. Could be several causes including an O2 sensor. Might just need some new plugs. The P0300 means multiple misfires, and there's a possibility that the misfiring is causing raw gas to reach the cat converter, making the system think that it's running rich. Double check your new sensors and consider a tune-up. Erase the codes then and see if they come back. Come back and give us a report. |
Well... it's been 4 days and the mechanic has NO IDEA
what's causing the check engine light to come on with the 175/300 codes...Geesh... G |
take it to a better mechanic one that under stands speed density fuel injection not mass air flow.
|
The mechanic told me they are doing some sort of a "compression cleaning" or something
like that. I think there is MORE to this than I'm being told. It's a 2002 Chrysler Concorde Limited Edition. It has 139,000 miles on it. Maybe the engine is shot! |
its not a cleaning issue they are wasting your money
this is the possible causes for that code. INTERMITTENT CONDITION O2 SENSOR HEATER OPERATION O2 SENSOR EVAP PURGE SOLENOID OPERATION O2 SENSOR SIGNAL CIRCUIT O2 SENSOR RETURN CIRCUIT THROTTLE POSITION SENSOR VOLTAGE GREATER THAN 0.92 VOLTS WITH THROTTLE CLOSED TP SENSOR SWEEP MAP SENSOR OPERATION ECT SENSOR OPERATION ENGINE MECHANICAL PROBLEM FUEL FILTER/PRESSURE REGULATOR (HIGH) PCM |
Well.... here's the latest...
After the "mechanic" installed ANOTHER 02 sensor and "said" the car was running fine... called me up an hour later and said the light came BACK ON! "supposedly" the car is giving an "intermittent" code or something. SO... Now I'm to take it to a dealership where they will do a "flash" (whatever) and reprogram the computer. HUH!!??!!??!! G |
that still wont fix it there is no flash aka computer upgrade that will fix this.
|
This is one reason why some techs get bad reps the people b4 them dont know crap and dont know enough when to say they dont know what they are doing and just mess more stuff up.
|
Well then...
What WILL fix it? I'm at my end with this. The car runs EXCELLENT but I do not trust it if the light keeps coming on and shooting all kinds of codes at me. G |
