NISSAN ALMERA IGNITION TIMING PROBLEM

2002 Nissan Almera • 150,000 miles

Dear Sir / Madam,

The Cylinder head gasket was replaced on this vehicle. I am getting the following error codes:

P0325 Knock Sensor B1 Circuit
P0335 CKP Sensor Circuit

The Check Engine Light is on. I deleted the error codes, however the error codes came back. The vehicle is starting and working fine but the check engine light remains on. Kindly tell me what is causing these error codes. Thanks

No, the scanner can only read the ignition timing but cannot set it as the ignition timing is computer controlled.

I was using an Autoboss V30 Scanner. There is a option "Ignition Testing". The Ignition Timing could have been increase or decrease at that moment.

However, the ignition timing came back to its original value on restarting. Can you tell me the main purpose of "Ignition Testing" on this Scanner?

The testing is for the advancing or retarding of the ignition timing. This might help in diagnostics and if you advance the timing too much, the knock sensor would tell the computer to retard it.
