Re: 99 Viggen -CEL P 0453 pressure sensor high voltage ?

Hello,
The p0453 should be a code for wiring or a failed sensor. The pressure sensor is connected by crimps in the wiring harness to the throttle body and charged air pressure sensor. If either of those is internally shorted it could be your problem. With the pressure sensor unplugged do you have 5v on pin 1? With the pressure sensor unplugged do you have ground on pin 2? Also remember that the wiring for the sensor goes through the big blue connector on the drivers side a pillar and through the big grey connector behind the glove box. Good Luck, Bernie
