I have a 1998 chevy s10 LS extended cab pick up with a 4 cylinder/2.2 Motor.... I have a code PO452.... I replaced the fule tank pressure sensor plug .... the check engine light came back on and it says PO452 ... how can I fix this issue ... thanks much Tim

Usually the sensor takes care of the problem. Make sure the connector is properly connected. According to the factory service manual, if the sensor and connector are OK, the problem is the PCM, but I haven't seen any PCMs going bad for that code.
-
i have on 2005 chevy impala. I have replaced the complete fuel pump assembly and I still have the code (PO452). any ideas on how to get rid of it?
-
1999 olds bravado with 4.3l. Replaced pressure regulator and also Replaced fuel tank pressure sensor and cleaned the plug. Still have p0452 code. Any other options?
-
Unfortunately I haven't had that problem before, but according to a national database of repairs for the same model, year and code, after the "Fuel Tank Pressure Sensor" the most common problem that triggers the P0452 code is the "Fuel Pump" and/or "Gas Cap"
-
Yes, more than likely the hole will set the code. What model and year is your vehicle?
-
Check the gas cap. This error can happen if the gas cap either doesn't seal or leaks, not allowing pressure build up in the tank. Really easy to check by changing to another cap.
