If you have high resistance in secondary ign. system (plug wires, ign.coil) this will cause this code to set. make sure you are using a high quality spark plug wire set. not from autozone!!! and denso non platinum tipped spark plugs. also use a diaelectric grease on plug wires to keep moisture out.

P0341 - Camshaft Position Sensor Circuit Range/Performance

This P0341 code basically means that the powertrain control module (PCM) detected a problem with the camshaft signal. The camshaft position sensor (CPS) sends a specific signal to the PCM for Top Dead Center on the compression stroke as well as signals indicating the position of the cam sensor. This is accomplished through a reluctor wheel attached to the camshaft that passes by the cam sensor. Any time that the signal to the PCM is inconsistent with what the signal should be, this code is set. NOTE: this code can also be set by extended cranking periods.

Symptoms: The car will likely run with this code set, as it is often intermittent and also because the PCM can often operate the vehicle in "limp-in/limp-home" mode even with a cam sensor signal problem. There may be no noticeable symptoms other than:
* Poor fuel economy (if engine runs)
* Possible no start condition


Causes: A code P0341 may mean that one or more of the following has happened:
* Cam sensor wiring routed too close to spark plug wiring (causing interference)
* Poor wiring connection at cam sensor
* Poor wiring connection at PCM
* Bad cam sensor
* Damaged reluctor wheel

Possible Solutions: Often relacing the sensor fixes this code, but not necessarily. Therefore it's important to check the following:
* Check that the wiring isn't routed too close to any secondary ignition components (coil, spark plug wires, etc.)
* Visually inspect the wiring at the sensor for any burn marks, discoloration indicative of melting or chafing
* Visually inspect the cam sensor for damage
* Visually inspect the reluctor wheel through the cam sensor port (if possible) for any missing teeth or any damage
* If reluctor isn't visible from outside the engine, visual test can only be done by removing cam shaft or intake manifold (depending on engine design)
* If all checks out okay, then replace the sensor.

Code: P0133 - O2 Sensor Circuit Slow Response Bank 1 Sensor 1


is this a 4 or 6 cylinder?
if a 4 cylinder it will only have 2 o2 sensors
V6 will have 4 o2 senors which the sensor will be the right side of the engine first sensor.
1st sensor on exhaust, I recommend if you change one change all, as this will make the computer when it rechecks the system you have all clean/fast responding sensors.

if you have a slow response it means the sensor is dirty and not reading well, which is usually caused by minor misfires that the engine computer dismisses, so a tune up would be recommended too.
