I got these codes about a month ago and reset it and last night I got them again. Just wondering what would cause my Temp sensor to go off. The temp gauge stays in the middle range, so I am confused. Also I have never heard my engine knock(allways use premium) and I am not sure why I am getting the knock sensor code. Maybe my sensors are going bad. Any ideas on how to fix this and how much it will cost???

 

If your knock sensor detects detonation, I believe that the code will pop up.

What kinda gas are you running?

-Shing

 

I use premium 91 and up usually 93

 

I'm not too familiar w/ the Max error codes.

103.. is that for the coolant temp sensor, fuel temp sensor, exhaust gas temp sensor, air intake temp sensor.. which temp sensor?

 

coolant

 

I ALWAYS use Sunoco 94. (and it loves it!)

With my 95 SE, about once a month my knock sensor goes off.
In Canada, that code will not fire off the MIL (malfunction indicator light), and the car runs great.
(Cal cars are different)

I don't know how long it has been doing this, but it has not been a problem.

Keep in mind, if the knock sensor is firing off a code, it DOES NOT MEAN IT IS DETECTING KNOCK, it means the signal received by the ECU was too high, or too low.
