P1320 INFINITI -

Question

Replaced the cam sensor and checked all coils replaced 3 of them , service light goes off after we clear the code but after key is shut off and engine restarted the same code comes back on 1320

Answer 1

The P1320 code means that the resistance for one or more of the ignition coils is out of factory specifications. It's very possible that you may have another bad ignition coil. The only way to find out exactly which coil is the bad one is by using an oscilloscope and monitor the signal from the Engine Control Module (ECM) to the ignition coil.
