Answer 1

camshaft sensor in located on the back left lower part of cylinder head you will need an remove the sensors mounting bolt disconnect sensor electrical plug once done pull sensor out. reverse to install note always disconnect negative battery cable before remove sensor

I follow the following message on my 2004 Forenzar to remove P0342 successfully.

My car had the symptoms of an intermittent check engine light illumination when engine temperature was warm up to certain point. I hooked it up to a CAN (computer area network- 0r network of computers) compatible scanner and got code P0342. This indicates low input from the camshaft position sensor. This code can be removed after 2-3 more miles warm up. The P0342 repeated after warm up every trip recently so I decide to replace the bad part. I did a little checking of ohms between each terminals to verify this valus could be different from a bad one in my car and went to work replacing the faulty sensor. I found that many web site has this parts about 50-65 USD.

I hope the new sensor is better than the OEM (Original Equipment Manufacturer). This is likely to be that the new one is updated and therefore less likely to fail. The car only had 85,000 miles on it and Suzuki wouldn't cover it under the power train warranty.

Here's how to replace the cam sensor.

1) To replace the sensor you remove the top engine cover by two allen screws on top.

2) Next remove the air filter box.

3) After that raise or otherwise support the engine slightly to take the weight off the passenger side engine mount.

4) Now remove the fasteners from the top of the mount. The mount may be siezed and require an orange rubber mallet. Now you can access the M6 10mm head bolt that secures the timing cover in place.

5) Take it and the plate out. Now you have access to the sensor.

6) Note the whole timing cover doesn't need to be removed.

7) Inside you'll see the bottom brassy metal half of the sensor.

8) There's a special "E" socket required to remove the bolt on the sensor.

9) I say "E" because that's what the sockets say like "E8" it's basically a female torx bit. Torx are like "T55" etc. You can buy a set at your local auto parts house cost about 13 USD. They look like a star as apposed to a hexagon.

10)BE CAREFUL! While you remove the bolt have a magnet wand right there to catch it. If you don't you could drop it into the timing cover to eat your timing belt. I do not have magnet socket. I inserted paper to cover all holes to avoid the start screw drop into timing belt box.

11)No big deal, just 2 hours of extra labor you don't have to do. OK now you can pull out the sensor from the top and unplug it! You now just need to wiggle the new one in and mount the "E" bolt back into it. I use a small mirror to aim the screw hole. I also tight the screw head by one layer paper between socket. Then I remove all paper out of timing belt box.

12) good luck
