Code numbers

[hihobruce]

2001 boxster S Got check engine light. Reader showed P0102, P1137, P1126, and P1133. I cleaned the MAF sensor,but light came back on. I have no idea what P1137 (clutch pedel?) means. I think P1137 and P1133 are c02 sensors. Can anyone tell me which sensors they are or should I change all four plus the MAF sensor? Thanks for any advice you care to offer. Bruce

P0102 Mass Air Flow Sensor - Below Lower Limit

P1126 and P1133 indicate reaching fuel enrichment limit - an indication of an air leak in the intake system for both engine banks

P1137 Clutch Switch - Signal Implausible

This car seems to have a couple of different problems.

Start by cleaning the MAF again and clearing the codes. If that doesn't cure the P0102, then replace the MAF.

Once the MAF is working, then clear the codes to see if the enrichment codes come back. If they do, you'll have to find the air leak in the intake system.

The clutch code is likely one of the two clutch switches.
