2013年6月5日 · Well yesterday the Check engine, traction control and blinking cruise control light came on. I checked to see what code its throwing and its P0451. Anyone have any input on this? I have almost 19000 miles on it. That code could simply be a loose gas cap.

2014年10月27日 · I keep getting this code P0451. EVAP emission control system, pressure sensor range. Happens once or twice a week and stays for a day or two. I brought the car to the dealer and they ran their checks but didnt find anything, then proceeded to tell me to flash back to factory to find the problem.

2020年4月2日 · It means that your Subaru WRX's EVAP system has a pressure sensor that is malfunctioning in some way. P0451 is usually caused by either a bad EVAP pressure sensor, a clogged fuel tank relief valve, EVAP lines, EVAP wiring, or a bad

2012年9月6日 · 2012 WRX CEL P0451!!! So I got in my car to go to work this afternoon and my engine light was on and the cruise control light was flashing. I plugged my scanner in to read it and I got a CEL of P0451-EVAP emission control system press sensor range.

2013年9月8日 · Since I got my V3 yesterday, I am also noticing, the hill start, abs and check engine light will illuminate without the cruise and no codes stored, I wonder has anyone else had issues when leaving things like an accessport plugged in?

2022年7月9日 · Code is P0451, idle is shakey and a bit high. Mechanic said it is a vacuum leak, any thoughts can’t go in anywhere until Monday. I had a rough idle, took out my MAF and gave it a quick cleaning with MAF cleaner and it cold starts so much better. I would check the gas caps condition first, and then clear the code.

2023年11月8日 · I have a 2013 wrx and I started my car with rough idling and a P0451 code that reads "Evaporative Emission System Pressure Sensor/Switch".
