hholmesauto Posted December 19, 2020 Report Share Posted December 19, 2020 13 Ford Edge 3.5 l p0352 Coil Over Plug code. Changed plugs, coil pack, compression test ( avg. 160 every cylinder), tested wires to and from, also unrelated tested the Fuel injectors and the wiring and had computer reprogrammed. Erased after each, DTC P3502 returns. Any suggestions? I believe that the PCM or ECM is the problem. I think when the #2 coil over fried itself it also fried the circuit. Even though the wires check out. I could be wrong. That's why I' joined this board. Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted December 19, 2020 Report Share Posted December 19, 2020 yes, most likely the driver circuit is toast, and you need to have the pcm reprogrammed by a service such as circuitboardmedics.com how many miles when this code first popped up? how did the coil look when you pulled it out? any pics to share?

enigma-2 Posted December 20, 2020 Report Share Posted December 20, 2020 There's also a possibility that the problem concerns the wiring running to the coil. Connection may be corroded or burned. Quote Link to comment Share on other sites More sharing options...
