Knock sensor problems
 
Ok.... This has been an nightmare

i am getting a code knock sensor circuit 1 (bank 1) p0325 and baro sensor circuit p1195.

I have checked the knock sensor by putting my meter on the lead to the sensor and setting for milli a/c volts. Taped next to sensor and getting a rise of 10 mili volts. Its defianalty rising and not rising during taping.

The baro sensor i have not really invesigated other than seeing if vacuum lines attached.

I was going to check the wiring all the way back to the ecu but i cant get enough slack in the wires to get the ecu out. Not sure if i could get the connector hooked back up. Very tight.

If i clear the code and it immedialy comes back evne without starting the engine. The baro code requires me to run the engine for it to post.

WELL I ALSO FOUND THE AIR INTAKE SENSOR IS "OPEN" PER THE MANUAL. THE MANUAL STATES THERE SHOULD BE REISISTANCE BETWEEN THE PIN AIR ROOM TEMPATURE. I HAVE NONE.

I THINK LIGHTING HIT THIS CAR. F ME!!!

I HOPE THIS WILL FIX THE BARO PRESSURE SENSOR ERROR CODE.

ANY SUGESTIONS?:mad:
