Po452
 

SOOOOO this is the code...
Evapo leak? or sensor problem is what mr autozone said...

Where do I start?


Also my rear suspension is creaking like an old person!!! could that just be bushings?

OBDII Code Index --> P0452 - Evaporative Emission Control System Pressure Sensor Low Input

THANK YOU

I searched PO452 and found nothing

Try a 0 (zero) instead of an 'O'. :icon_wink:

Just realized that... Guy at Autozone, said it would need new lines, while second guy at different autozone said it could be caused by "overfilling" my tank, because I mentioned I top it off everytime.....

He also noted that its a 46 dollar sensor and that he couldnt clear the code... But he then coughed *remove the ground* if its bothering that much...

Thanks again, I will be checking this out, and he also mentioned if there was a problem that I would start smelling gas...

KYLE SAVES THE DAY!!! AGAIN!!!

I also have a p0452 on my 99 blazer. Were you able to resolve the issue?
