GenVibe - Community for Pontiac Vibe Enthusiasts

Hello there. (1) I have 2004 awd Pontiac vibe with 204,000 miles. Recently, I have all the 4 cylinders misfire. So I replaced the throttle body, vvt solenoid , cam sensor, plugs and the coils. All those couldn’t help. The timing might have screwed up but not sure yet

(2) I just bought 2007 fwd Pontiac vibe 140,000 miles and has P0452 code (Fuel Tank Pressure Sensor). I don’t want to start replace parts until I’m sure of the problem. Can anyone help me please? Any help will be highly appreciated. Thanks

Welcome dantayuba!

Check compression on your 04, look for vacuum leaks. Any codes?

P0452: Did you unplug the battery to see if it resets itself?

The 04 codes are P0301, p0302, p0303 and p0304

for the 07 code p0452, yes disconnected the battery and I also use a scanner to erase it but nothing happens.

I assume you used Toyota parts or Pontiac parts. Check for vacuum leaks, fuel pressure, clogged cat. Anything that could affect all cylinders at once. Clean all electrical connections you can access under the hood. A bad alternator could cause such misfires too.

Replace the sensor with a known good one.

The surprising thing is that the o4 p0452 sensor is on top of the fuel tank but the 07 sensor is no where to be found. Could that be the same as the purge valve? or do you know where the sensor can found on the 07? could that be attached to the fuel pump rather?

I am not 100% sure. The sensor should be on top of the tank or inside the tank.
Unfortunately my searches don't bring up a direct hit for Corolla, matrix or Vibe.

carsntoys.net seems to cover everything but P0452. Still, it might be a helpful source to you.

But Peter Finn in his videos refers to a piece under the hood as the EVAP sensor. I thought it's the control valve. Look around the intake tube. Sometimes it is next to the tube and sometimes attached to the tube itself.

I hope someone else has better info for you.

Thank you for your time.
