RICH I HAVE A 96 ELDORADO NORTHSTAR ENGINE CODE SHOW THAT P0340 IS CAMSHAFT POSITION SENSOR A,BANK 1 MALFUNCTION I REPLACE IT NEW THINKING THAT IT WAS BAD IT STILL HAVE THE SAME CODE CAN IT BE THE ICM PLUS OTHER CODE P0717 CAN YOU ME FIND PROBLEM

These are camshaft position sensor codes. Replace camshaft sensor.

I am not sure what "slip n tcs" means but on the 2005 nissan maxima the code P0340 is for the camshaft position sensor circit on bank 1, which is in the rear of the engine compartment. Code P0345 is for camshaft position on bank 2, which is in the front of the engine compartment. The images show the Cyl banks and a cam sensor.

P0340 OBD-II Trouble Code - Camshaft Position Sensor Circuit Malfunction

This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.

Symptoms can include:
* Hard starting or no start
* Rough running / misfiring
* Loss of engine power

Causes: A code P0340 could mean one or more of the following has happened:
* a wire or connector in the circuit could be grounded/shorted/broken
* the camshaft position sensor may have failed
* the PCM may have failed
* there exists an open circuit
* the crankshaft position sensor may have failed

Possible Solutions: With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
* Visually inspect all the wiring and connectors in the circuit
* Check for continuity in the circuit wiring
* Check the operation (voltage) of the camshaft position sensor
* Replace the camshaft position sensor as required
* Check the crankshaft position circuit as well
* Replace circuit wiring and/or connectors as required
* Diagnose/replace the PCM as required



P0133 OBD-II Trouble Code - Oxygen Sensor Circuit Slow Response (Bank1, Sensor1)

This involves the front oxygen sensor on Bank 1. This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use.

Symptoms: You will likely not notice any drivability problems, although there may be symptoms.

Causes: A code P0133 may mean that one or more of the following has happened:
* The oxygen sensor is faulty
* The wiring to the sensor is broken / frayed
* There is an exhaust leak

Possible Solutions: The simplest thing to do is to reset the code and see if it comes back.
If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:
* Check and fix any exhaust leaks
* Check for wiring problems (shorted, frayed wires)
* Check the frequency and amplitude of the oxygen sensor (advanced)
* Check for a deteriorating / contaminated oxygen sensor, replace if necessary
* Check for inlet air leaks
* Check the MAF sensor for proper operation


Hope this helps (remember to rate this answer).

this car has but one bank, the cam sensor is under the intake manifiold on the drivers side.

O2 Sensor Circuit No Activity Detected Bank 1 Sensor 1

the bank one sensor is either disconnected are faulty.

the bank one sensor is the sensor in the exhaust of the rear cylinder bank of the engine cylinders 1,2,3, the sensor is the one before the catalytic converter. U will need an O2 semnsor socket to remove it or in some cases a 7/8" open end wrench will do.

Track the p0340 first camshaft timing is very important and could possibly cayse your other codes,Call your local GMC dealer I think I remember a bulletin about this code.
