Took my '96 Maxima SE in for annual MD emissions check and failed - check engine light was on, so no suprise, (at least I get three months of better weather to work on the problems). The test results and error codes provided by the emissions check printout were:

Mil Engine off: Pass

Mil Engine on: Fail

DLC Tampering: Pass

OBDII Communication: Pass

Mil Command Status: Fail
* P0325 - Knock Sensor 1 Circuit Malfunction (Bank 1 or Single Sensor)
* P0135 - O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
* P1447 - Manufacture's code

I am assuming that the P codes would be the same if I had checked them myself. Can anyone provide addtional detail as to what these mean and what has to be fixed/replaced?

I attempted to use the decoder at http://vbxmaxima.8m.com/ecudecoder.html but it does not go over 13 for the first number nor 15 for the second. Thanks for any input.
