p0453 evaporative emission control system pressure sensor high input Chevy s-10 Bazer. I have a code P0453 evap high pressure. Vehcicle very difficult to start after sitting for several hours. Will start again if sitting for a short time. Has a new fuel pump, regulator and fuel filter. How do I correct this code? Will this correct the problem starting? Evaporative Emissions Control System Pressure Sensor High Input  The EVAP (Evaporative Emissions) System allows fuel tank vapors to be purged into the engine and burnt rather than expelled into the atmosphere as harmful emissions. The EVAP system contains a pressure sensor to check the integrity of the system. Periodically, the EVAP system performs a pressure test to check that there are no leaks in the system. It uses this sensor, also known as a fuel tank pressure (FTP) sensor to check for leaks. Basically P0453 means the PCM (Powertrain Control Module) noticed the EVAP Pressure sensor or FTP is indicating a higher ...

code p0131 p0137 p0151 p0157 p0171 p0174 2015 cadillac SRX i recieve code p0131 p0137 p0151 p0157 p0171 p0174 every time i clear it they come back in one minute The P0171 and 174 are most likely setting because of the oxygen sensor issues. The other codes are for each of the four oxygen sensor signal circuits and set when the signal circuits are at or near zero volts. This could be a wiring issue, the sensors themselves, or possibly an internal failure in the powertrain control module. Sensor failures aren't likely to be the case if all four codes started setting at once.Is the car no longer under basic warranty?. This will help.Thanks.
