Mine is a 2003 Boxster and I have a cam position sensor on the left rearbank and on the right forward bank behind the passenger seat. If you are looking at the position sensor on the left forward end behind the driver then you will find the other one on the rear of the right bank on the passenger side. Of course with the forward engine cover removed you should be able to see if there is also a position sensor on the right side front, just behind the passenger seat. If there is one there it will surprise me because they normally alternate one side forward with the opposite side on the rear.
Nothing special other than metric box end wrench or socket to take off the front engine cover holding bolts and a screw driver, but for the front it is all easy and does not need a super flexible wrist to get to the sensor. You might want to use dielectric grease sparingly on the electrical plug contacts. Put a little in the female side of each contact in the plug.
This position sensor is on the front of the engine on the passenger side. It is readily visible and accessible by removing the front engine cover in the passenger compartment. The Bank 2 sensor is on the left bank on the rear of the engine and is accessed by removing the air tube from the air filter box to the engine.
Your advice is what my logic said to do in your steps 1-4 above. Do you have any ohmic values for using a digital meter on the position sensor to check for resistance or open? Seems like I remember that the line voltage should read about 5 VDC coming into the sensor. Thanks for the input.. DCR
To logray, It was eleven months ago that I wrote the above post that you so graciously responded to.. Well guess what??? Yesterday my 03 Boxster threw a check engine light again. But the box on it and it indicated a P0348 code again. This indicates the same cam position sensor has a high output again. Is it unusual for a cam position sensor to fail twice so close together? Being the code shows "high" input, do you have any ideas as to why this might be happening???? Things like a low or insufficient reading might indicate a crimped of crushed wire. I'm puzzled, any ideas other than just replace it again and hope for another year without a P0348 code and a CEL...
Thanks for your reply as it was helpful in solving the problem and getting the part. I pulled the front engine cover off and found one sensor on the right bank behind the passenger seat. I unplugged it and cranked the car with the durameteric cable plugged in and found a P0343 Code. I replugged the cable to the sensor and cleared the fault code. I then found the other cam position sensor on the rear of the left bank(looking forward). I had to take off the breather tube between the filter box and mass air sensor housing to get my hand down behind the left bank. I then used a mirror to confirm that it was a cam sensor. I unplugged that one and cranked the car and it threw a P0348 code which is the one that had been turning the CEL on. I ordered the sensor that you told me would work and installed it and so far no more P0348 codes. Thanks for your help. "The Wrench Bender"
I have a 2003 Boxster and have recently started getting a CEL. The OBDII code reader shows P0348 as Camshaft Position sensor A Circuit High Right Bank. From you experienced mechanics. Is this on the right side and where is it? All my research indicates that on the 2003 and up engines it is on the front top around the front end of the right cam????? Which way is the best to access and change the sensor? Next question is about the replacement part. Parts research for this sensor shows OEM non dealer parts like Beckley and Arney that range from around $92 to Standard at $172. Any experience out there on these parts???? Thanks in advance
Pilkington is good glass. However, if your are a purist and just must have the Porsche numbers, or the installers did not do the job correctly then you will not be satisfied. I have had Pilkington windshields installed in several of my vehicles over the years and they were perfect matches.
Can anyone advise what are the correct Bosh plugs, per the factory manual for the 2003, 2.7 Boxster engine? I read many opinions about what different people like, but no one seems to specify what the factory specs call for. Thanks
The CDR 23 radio needs to have the PST2 hooked up to coordinate the radio internal code with the one in the instrument panel. This is usually a quick dealer fix. This radio does not have a code that can be reset by the owner. This situation occurs when you disconnect the battery or remove the radio and reinstall it. This is an anti-theft feature.
