Had a code for the cam shaft sensor. I changed it and the next day it showed up again along with an 02 sensor code and a 0153 code. I should be getting 15 psi on my procharger but only goes up to 5. Any suggestions on the problem? Thanks.

 

what are the actual codes for the cam shaft sensor and 02 sensor? The 0153 code suggest that:

"The HEGO Monitor checks the HO2S Sensor frequency and amplitude. If during testing the frequency and amplitude were to fall below a calibrated limit, the test will fail.

Causes:
* Contaminated HO2S sensor.
* Exhaust leaks.
* Shorted /open wiring.
* Improper fueling.
* MAF sensor.
* Deteriorating HO2S sensor.
* Inlet air leaks.
"

 

0340 code for it

 

the 0340 is more often than not the alternator. take it to autozone and i guarantee your diodes are bad. when the diodes in teh alternator go, the camshaft sensor gets interference and trips the code for it. personally, i just learned to live with mine on rather than spend 200$ on an alternator. my car has had that CEL on for well over 1 year and theres no adverse affect on my car. starts first time every time, battery charges well, and holds charge. so i said f*** it
