im pretty sure the temp sensor is on the drivers side head.. the other one is a temperature sending unit, which is on the water pump

The temp sensor in the driver's side head does not connect to the PCM, and therefore cannot throw any codes. The one in the head just connects to the temp gauge in the dash.

Check the one in the water pump.

^ +1. The one in the head is ONLY for the gauge. If you've got a code, then its the one in the water pump.

The sensor in the "head", is actually in the block. Just thought id throw that one out.

The temp gauge sensor is in the head, the 'knock' sensor is in the block.
