Question

I got the engine code P2074 on my 2005 Chrysler PT Cruiser 2.4L, no vacuum leak, changed the MAP Sensor, and tested the TPS as stated when the butterfly opened volts went down to 2 volts changed TPS still not running, and have the P2074 code. can you check the ECM module?

Answer 1

There really isn't any check for the ECM, what you have to do is eliminate the other options. It is possible you have an issue with the PCM.
