2000 Chevy Blazer 6 cyl Four Wheel Drive Automatic 150000 miles
I have a P0452 code popping up on my blazer.
Autozone code reader gave me these details:
Definition: Fuel tank pressure sensor condition
The evaporative system sealed condition is monitored by this sensor
Fuel Tank pressure sensor defective
Check connector and wiring
Check hoses and fittings
I replaced the gas cap but I still get the error. Im not sure what wires and hoses to check so I want to try to replace the fuel tank pressure sensor.
Someone told me that with the 2000 blazer you don't have to drop the tank to replace the sensor, you can just reach your hand on top of it and get it. Is this true? If so how will I tell that I got the sensor?
First make sure your gas cap clicks 3 times when tightening and then make sure you don't have any holes in the vent or filer neck hoses. Then go to your evap cannister and you'll see a red valve. That is what you need to see.
