2003 Nissan Altima Diagnosis

Hi mikeb57,

Thank you for the donation.

Since wires had been chewed, there is a possibility the cam angle sensor is broken at some place.

Is the code P0340 or P0345?
Your vehicle is stated as six cylinder, that means it is 3.5 L and it has two cam sensors. Which did you replace?

Sensor A bank 1 was replaced. The code is P0340.
By the way, the wire that was chewed and repaired went to the knock sensor. That code is no longer appearing on the report.
After repairing the wire, the car started with some difficulty. It no longer appears to be stalling so the problem now existing is the time it takes to start. As I said the cam sensor was replaced and the same code still keeps showing up.

When the codes keep showing, it could either be a fault with the sensor, its wiring circuit or the PCM.

Do the following test first. Check continuity between sensor and PCM, terminal 65 ( Yellow wire). Check the ground connections ( Black or Black/White) Check Red/Green wire for battery voltage when ignition switch is turned ON.

Could you enlarge that schematic at all? When I do it on this end it is not clearly legible. Thanks

Sorry the site is not friendly with diagrams. I will email the schematic to you so you can have better control over it.

Hang on and it should be there soon.

Do auto electric shops have any way of testing sensors to see if they are good?

Yes, there are diagnostic equipments for testing of sensors.

You have been very helpful. Do you have access to the list of parameters for checking ohm resistance from pin to pin on the sensor?

The main aim of this site is to help in whatever way we can and we would never turn down any questions if we can help it.

Yes, our database do have specifications for sensor resistance and voltage ranges. Let me know what you requires and I will get it for you.

For the cam sensor previously discussed.

Here you go. Hope it is legible. This site is not too friendly with diagrams and are often resized too small.
