Help guys, not sure if this is the right place for this, but my 09 SRT has been running crappy for a few weeks and I'm lost what to do next. It has a Vortech SC, Kooks long tubes, bigger injectors, boost a pump, Dynaflow 3" exhaust and makes over 600hp. It's been bucking, jerking, and just being a ***** to drive. This morning I swapped out all 4 02 sensors, and the codes came right back. The say high heater voltage on sensor 1, bank 1 and sensor 1 bank 2. What is the next thing to check? Not even sure it this is in the right forum for this. Thanks in advance. Jeff
A P0052 trouble code may be caused by one or more of the following: A short in the heater circuit in the sensor, failed O2 sensor heater wiring/connectors, broken/frayed wires leading to a sensor and/or relay, or a failed PCM/ECM. To pinpoint the problem, you should inspect the wiring and connectors leading to the sensor. Also if equipped with a heater relay and fuse, you'll want to check those as well. Use a digital volt ohm meter to: check for 12 volts at the heater circuit feed (hint: unplug the sensor and check at the wiring connector to do this measurement) check the ground circuit for continuity measure the resistance of the heater circuit (done on the sensor itself) measure the resistance and voltage of the wiring (Refer to a service manual for the correct specifications, volts, ohms for your Challenger).

They were in the title, but must have been cut off when the item was moved. They were were 0032 and 0052.
