    2008 Chrysler 300 Limited - Car has 240k miles (3.5 engine) and started throwing P0138 code. Dealer changed that sensor, drove it for a few days and CEL came back on. Had P0132 code and subsequently got P0152 and P0158 codes. The other 3 sensors have been replaced with OEM parts and the car is still throwing codes. Happens on cold starts. It's been suggested that the ECM may be bad, but before throwing more parts at it I thought I would post the problem here. Has anyone seen this before?

    The car has been great up to this point and maintenance has always been up to date.

    Thanks in advance for any help that is offered

    Correction on the codes, 2 I listed were incorrect...should have been P0032 and P0052 not P0132 and P0152.
