What make , model and year vehicle ? engine size as well . P0351 Ignition Coil Primary Secondary Circuit Malfunction . Could be the wiring ,coil , or the transistor inside the PCM - engine computer . Videos on youtube showing how to diagnose this code . Search P0351 .
You'll have to look up the actual procedure to test the coil for code 351. The code means the computer is not able to fire the coil on demand which could be caused by several things, including a faulty computer. It could also be a problem with the wiring between the coil and the computer.
sounds like this engine light has been on for a while and codes are piling up, lets start with the po351, note all codes should have a po or a p or b in front of #s.anyway lets go, first is po351 which means you have a bad # 1 ignition coil, replace the coil and check the connection and this will solve that code. next is po420 cat eff below threshold, this means the converter is not working good anymore, but bad oyxgen sensors will cause this code if they are bad and not reading exhaust correctly, you will need to have the o2 sensors tested and also make sure converter is not rattling loose inside shell if it is then cat is bad not o2 sensors, and last code is po545 is ac clutch relay circuit this may be due to a bad ac compressor clutch a blown fuse or bad relay. hope this info is helpful.
