Hopefully where the manufacturer installed it. Good luck.
where is knock sensor located on a 99 Silverado 1500 4.3
Bank 2 is the side of the engine where the #2 spark plug is. On my 99 Silverado it's on the passenger side.
You may have an ABS sensor going out at one of the wheels.
It is behind the starter. you can not see or get to it until you remove the starter.
You'll need to drop the tank. Then the fuel sensor/fuel pump comes out through the top.
on a 99 model there are two of them and its located under the intake. quite a bit of work but not bad.
P0452 indicates that the Fuel Tank Pressure(FTP) sensor circuit has low input voltage on that circuit. Possible causes: Fuel tank pressure (FTP) sensor completely submerged in liquid fuel. Inside contamination of the electrical connector on the FTP sensor. FTP short to SIG RTN or PWR GND. Damaged FTP sensor. Damaged PCM.
P0451 - Evap Emission Control System Pressure Sensor Performance Improving my answer - P0451 - intermittant open or short in the fuel tank pressure sensor ( FTP ) or the FTP sensor signal
how do you replace ambient light sensor on 2002 silverado
where is the cam sensor located on a 2001 silverado ?
P0453 - Evaporative Emissions Control System Pressure Sensor High InputA P0453 DTC trouble code may be caused by one or more of the following:Open on Fuel Tank Pressure - FTP - sensor signal wireShort to voltage on FTP sensor signal wireBad FTP sensorAbnormally high pressure in fuel tank due to blockage in EVAP purge hoses or overfilled tankLoose/damaged FTP sensor connectorLoss of ground to the sensor
That year did not have a MAP sensor.
