What's the mileage on your car/engine? The Bentley Service Manual indicates only a "check" of the Timing Belt at 80,000 miles.
My check engine light came on while driving today, I didn't notice anything wrong until i looked down and saw it, then I drove home fine with no problem, but I'm scared to start it again. I checked the code and got P0343. Should i start by replacing the sensor and how? or do I need to replace the timing belt? (don't know when it was last replaced). I took pictures of the timing belt in case that helps.
Verify that the engine is still in time and the belt has not jumped.
Replace the cam sensor. You have to take the belt off to do it, might as well replace the belt, tensioner, and water pump at the same time. Regardless of what the Bentley says, I usually recommend timing belt replacements on these between 90-100k miles.
At 86,000 mi., my '02 AZG threw P0343 and wouldn't rev past 3200 rpm. Replaced the cam position sensor, problem solved.
There is a DIY here but in my opinion it's much easier to just remove the cam gear and finesse the new sensor in. (Leave the valve cover alone.) Do mind the tabs.
Hey, I'm working on a 2004 Jetta 2.0L SOHC (BBW engine code), and I'm trying to figure out where the Cam sensor is located... dealer faxed me a picture, but it's just parts on a page, no diagrams as to what goes where. It's not like the one above, this one has a different looking cam gear on it.
