Question about 2001 Volkswagen Passat
Well code 11 means the computer thinks the cam timing is too far advanced, which could be a timing belt issue.
Code 34 is supposed to be a problem with the turbo if your car has one.
Trouble codes seldom mean a sensor has failed.

Testimonial: "Okay the codes were for the camshaft sensor and camshaft over advanced. I replaced the camshaft sensor in that did not fix the problem. I'm going to try changing the oil next. But if that does not work what else should I try next? Thank you everyone for your comments and advice"

well i know on the v6 that is true you replaced all of them. Not sure of 4 cyl but seems like it should be the same. Also I know on the v6 the variable valve timing set up sometimes did some weird failures triggering a cam sensor code. It could be anything from sludgy oil hanging up in the vvt hub or clogged passages or bad solenoids. but before going into all that(well besides maybe an oil change) I would go for the crank sensor.

It is located under the water pump. Make sure when you remove the sensor that you rotate the crank shaft and look in the hole to make sure the pick up magnet is still in there. Sometimes they come loose and cause a no start or long crank. You will need to have the code cleared still.

when you are looking at the engine pull off the plastic cover on top then the front cover that covers you timing belt there is a wire harness tha goes right to it in the left upper coner two ten mil bolts and it comes off careful not to drop bolts down in belt that could be bad. it is that easy

OK check the CMP sensor connector for cleanliness, sometimes oil can get in and disrupt the signal transmission to the ECU. Check the wire loom continuity all the way back from the CMP to the ECU. If the error code persists remove the cam sensor, clean its tip of any debris and refit.

Testimonial: "Thanks joe2mercs...you had the problem diagnosed correctly. Cleaned and light has not come back on. U saved me a lot of $."
A code P0011 refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module, also called an ECM). That consists of a few different components but the P0011 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is above a set limit (over-advanced), the engine light will be illluminated and the code will be set. The "A" camshaft is either the intake, left, or front camshaft.
Most likely a P0011 DTC will result in one of the following: hard starting, poor idle, and/or stalling. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.
A P0011 DTC trouble code may be caused by one or more of the following:
Incorrect camshaft timingWiring problems (harness/wiring) in intake timing control valve control solenoid systemContinuous oil flow to VCT piston chamberFailed timing valve control solenoid (stuck open)
This DTC code is a result of a mechanical fault of the VCT unit or related components, so there is no need for electrical diagnosis. Refer to vehicle specific repair manual to perform component tests for the VCT unit. Notes: Dealer techs have advanced tools and the ability to follow detailed troubleshooting steps, including the ability to test components using a scan tool.
