Engine light came on for a few days and RPM gauge stopped working properly; then light went off and gauge worked okay for another couple days. Engine light is on permanent now and gauge needle stays on zero, but jumps up once in awhile when driving.

Car seems to run same. I got a Scanner code of P0320; ignition failure sensor code (IFS). If I replace sensor will that remedy problem?

I love this site

It's either IG sensor or wiring/plug issue or PCM. I would check plug and wires and if good replace sensor. The sensor is located at the rear of the engine. Here is a diagram to show you where it is (below).

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken
