DTC - 34 MAP Sensor Circuit Error (Signal Low Indicating High Vacuum)

The ECM uses the Manifold Absolute Pressure (MAP) sensor as an indication of engine load. High voltage would indicate low engine vacuum and higher engine load. Low voltage would indicate high engine vacuum and lower engine load. The ECM uses the information from this sensor to help calculate fuel delivery and spark timing.

Fault Code Description:
* 34 - MAP sensor circuit error (signal low indicating high vacuum)

Symptoms:
* Poor engine performance
* Engine running lean (not enough fuel, hard starting, lack of power)

Common Problems:
* GM MAP sensors do not commonly fail
* Due to erratic engine vacuum, other engine performance problems can cause a code 34 to set


Good luck (remember to rate this answer).

Ran low on oil car shut down added oil to right level car will not start. Took battery cable loose to rebot still willnot start


Seized !!! Engines are not computers, they will not "reboot"! You have heated two metals so hot that they have fused together inside the engine. Sorry you will need a new motor.

My 2003 crysler sebring stalled and want start back I geting the camshift sensor code I replaced it and car still wont start and still geting the code Would the timeing belt casue this


Yes a timing belt could cause this. Ususally if the timing belt breaks/slips the engine will have a different sound while cranking it over to try to start it. Does it sound different? Also, if possable remove the cam position senser and look at the tone wheel that the senser reads and have someone crank the engine to see if the tone wheel turns, if not the timing belt is most likely the problem. I have seen a few tone wheels have problems but it is not common. What engine do you have?

AFTER SOAKING SEVERAL TIMES WITH A CAN OF "KNOCK IT LOOSE" or something better than WD, then
  • Disconnect the wiring harness.
  • Unbolt the sensor mounting bolt.
