Just installed new harmonic balancer.I think the camshaft may be out of timing. I get a P0340 code car runs good. Need help with the code P0340

you need a proper scan tool and do a crankshaft camshaft corellation allignment.

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

The following conditions may cause this DTC to set:
If this DTC sets, there is a problem with the camshaft position actuator solenoid high control circuit shorted to voltage or the solenoid stuck open.

?€¢
An improperly torqued harmonic balancer

?€¢
A misbuilt or mis-timed engine

?€¢
A loose or missing crank damper bolt

?€¢
The camphaser solenoid stuck open

?€¢
The camphaser stuck in a position other than 0 degrees

?€¢
The camphaser does not return to 0 degrees within 16 seconds

code P0481 high speed number 2 fan relay control circuit. check for faulty fan 2 relay blowed fuse. code P0340 no camshaft position sensor circuit failure.possible causes camshaft sensor has failed or crankshaft sensor failed both sensor work together to control fuel timing and ignition timing.PCM has failed many things will cause that code.check sensor wiring connector for shorts or damaged.

Well, a lot depends on what is causing the P0340 Diagnostic Test Code (DTC) to set.

The Camshaft Position Sensor (CMP) is a pick-up coil mounted in the outer corner of the left cylinder head just below the valve cover (assuming your Camry is equipped with a V-6...you didn't say)
a one tooth signal plate is mounted to the outer camshaft. DTC P0340 sets when there is no signal recieved from the sensor by the Engine Control Module (ECM) either during engine cranking or engine running.
Possible causes are:
> Open or short circuit in CMP sensor circuit
> Faulty CMP sensor
> Defective starter
> Damaged cam signal plate
> Broken timing belt
> Internal ECM problem
Proper diagnosis required.

DTC P0340 - 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

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:

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day

Here is what each of your trouble codes means:

DTC P0108 MAP Sensor Range check High
DTC P0121 TPS Circuit Range/Performance Problem
DTC P0340 Camshaft Position Sensor Circuit Malfunction
Do you know how long each of these codes have been stored? Each one of these codes relate to a different part of the vehicle.

Your PO108 codes is probably a faulty Manifold Absolute Pressure Sensor
PO121 is a Throttle Position Sensor malfunction code
PO340 is a Camshaft Position Sensor malfunction code

I would not think that all 3 of these codes all set at the same time, just wouldnt make sense unless there was a problem with the Engine Control Module (ECM) causing all these codes to set at the same time.

DTC P0320 also have with this wrong.

DTC (diagnostic trouble code) P0340 is indicating a fault has occured in the camshaft position sensor system of the cars' electronic engine control system. DTC P0717 is for a transmission input turbine shaft speed. Typically these codes are unrelated. Both the sensors are variable reluctance devices. They have no moving parts and as such are robust and not usually prone to failure. But they can and do fail. Are either codes "hard" faults or are they in the continous memory of the computer? Does the P0340 clear itself when the engine is shut off and restarted? Can you cause the P0340 to reoccure just by starting the engine and with out driving it and revving the engine to 1500 to 2000 rpm for 1 to 2 minutes while in Park? The P0717, when cleared should only reoccure when the car is driven. If the camshaft position sensor has been replaced and still the same code occures make sure you have the correct information as to the meaning of this code in regards to your particular model year and engine. Does the engine have a camshaft position sensor for each camshaft? If so what is the DTC code for the other camshaft position sensor. Yes, the engine's computer (ICM, PCM, ECM, all terms for same thing) could be faulty but in most cases this is not the problem. Does the transmission seem to shift properly? You probably won't notice a differnece in the way the engine runs if the camshaft position fails due to the default stratagy used in the ICM. Wiring would be my next area of concern. Does the wiring for the camshaft position sensor and the transmission sensor go through the same wiring harness and could you have a poor connection at some point in that harness? Inspect the wiring and the hardshell connectors throughout the harness. Let me know what you find out. Thanks
