A/C off, code 528?

[JoesSHO]

I ran my codes today, and got the following:

114
116
528
565

I know the CANP is bad, I have to bypass or replace that.

The ECT I was unaware of, would that cause bad mileage? Like 15-19 MPG? Becasue of improperly reading the temp, and dumping timing like a bad O2?

The IAT I think is showing bad becasue it is about 35 deg here...

The 528? shrug
The A/C was not on at all- in fact the whole CC unit was off. ???

Thanx!

Anyone know why this code popped?

Clutch switch, not the A/C.

There is a two-part clutch switch. One serves as the starter interlock, the other signals the PCM than the clutch has been pressed to a) be able to control RPMs and b) dump the cruise control, if engaged.

Could the code pop becasue of the alarm locking into the clutch switch, and me turning the key without pushing in the silver alarm button, then doing it the right way?

The clutch switch works fine... ?

Thanx!

If the clutch properly disengages the cruise control, I wouldn't worry too much about the 528.

Hmmm, I'll try that tonight.

I think it had something to do with the alarm.

Thanx again
