Ok, so my intrepid is stumping me hard on this. It will crank and start perfectly fine. Shut it off, sit for a sec, crank and crank. Key off and back on, starts hard but runs perfect. Then it will start fine a few times.

Although it is a generic code, the specific repair steps may vary depending on the year, make, model, and powertrain configuration of the vehicle. When a code P is stored, it indicates that the powertrain control module PCM has detected an abnormality in the relay that supplies it with voltage. In this case, the relay sensor circuit is open, which can be interpreted as disconnected. It is a contact type relay that is activated by a signal wire from the ignition switch. This type of relay typically has a five-wire design. One wire carries constant battery voltage, another wire is for ground, a third wire carries a signal from the ignition switch, a fourth wire supplies voltage to the PCM, and the fifth wire is the power relay sense circuit. The PCM uses the power relay sense circuit to monitor the voltage of the power relay. If the PCM detects an open power relay sense circuit, it will store a code P and may illuminate the malfunction indicator lamp MIL. A P code should be considered severe and addressed accordingly. Delayed or no start Inoperative electrical accessories Engine drivability issues. You will also need a reliable source of vehicle information that provides diagnostic flow charts, wiring diagrams, connector face views, connector pin-out charts, and component locators. Additionally, you will require component and circuit testing procedures and specifications. All of this information is necessary for a successful diagnosis of a code P

P is a relatively rare OBD2 trouble code. This includes the Chrysler PT Cruiser. If your PT Cruiser is still running with this code, we strongly recommend against driving with it. If the PCM power relay fails, your vehicle will not run properly. They stand for engine control module and powertrain control module, respectfully. An open circuit is a circuit that has not been completed. With this code, most of the time, the engine will not start or run. Remember, the circuit that senses the voltage at the power relay is open. Or, the power relay is working just fine and the sense circuit has gone bad.

P is a relatively rare OBD2 trouble code. While any car or truck can have this code, it is most prevalent in vehicles made by Chrysler. If your vehicle is still running with this code, we strongly recommend against driving with it. If the PCM power relay fails, your vehicle will not run properly. They stand for engine control module and powertrain control module, respectfully. When you have P, it has detected an open circuit. An open circuit is a circuit that has not been completed.

I am very happy to meet you guys and I love working with you! If you recall, at first it was just the TCM replacement that did the trick for me for about 3 months. Recommended Communities. I agree, I think all the sensors are in good shape because if the Crank sensor wasn't working properly, it wouldn't work while jumped. Often high or low voltage in circuits relates to grounding issues so you can see a possible relationship. Login To Our Portal. Battery is relatively new, charged it up and is having a similar issue. I expect the timing fine, again because it runs fine when it turns over. This is the first BIG issue i've had with it. Send a private message to flamaui. Have you tried clearing the codes? Ok, so my intrepid is stumping me hard on this.

If this happens to your ride, we get your concern, but the key piece of advice is not to drive around too much with the code and figure out a solution quickly. Find out more about OBD2 codes research process.

I expect the timing fine, again because it runs fine when it turns over. Otherwise you are correct on the rest. How can this happen after 1 week of being parked? Joined Apr 18, Then I had to put it back in the shop for the same issues. Luckymac Replies. This required cutting wires in the PDC and reconnecting them. Top list. I took the SRT back to the dealer today for what I hope is the last time. Nilsson said:. With all 4 setting the same codes one would have to assume the problem is within the PCM input to drivers or bad IC chip. HIDs, halos, speakers, etc?
