2003 Chrysler PT Cruiser Repair Question
Chrysler PT Cruiser Sensor Problem
Answer
All of these codes can be set if the common 5 volts is missing to the sensors. Measure all three wires at the throttle position sensor. In this case you can unplug it and measure right on the terminals. Expect to find 5.0 volts on the center terminal, but you need to find it on one of the end terminals. If it's missing suspect that wire is cut or grounded. If it is grounded, the Engine Computer will shut the 5.0 volt supply down to protect it. Once the short is removed you usually have to cycle the ignition switch off and back on to reset it.
I found the problem. I had tested all aspects of the circuits they had ground and 4.8 volts reference..which is common due to internal resistance in the copper wire. I pulled all connectors off all sensors and found the cam sensor connector and coil pack connector were the same design. I switched the two around and all codes went away and car runs great and no longer overheats. Thanks for you time and efforts to direct resolution to my question.... Mectec2012.
I don't think I would have figured that one out. Very happy to hear it's solved.
