I'm getting a P0453 code that keeps setting and won't erase. I've read that this is evaporative emissions sensor input too high. I'm assuming this means that the sensor is bad. Since I don't want to remove the damn tank AGAIN after JUST replacing fuel pump about a month ago, please tell me that this sensor is NOT inside the tank and can be changed without pulling the tank???

got a 98 vdp . if you have a harman karman radio with the rear speaker. you can remove it and the sensor is 2 in to the left. little black thing that looks like it just pops out and pushes back in.( just looks like it ) might try later and see
so the issue was absence of wiring? since i am not a mechanic with low knowledge in repairing cars, i thought that it might be faulty ventilation system, or valve or whatever that keeps the pressure in tank in normal limits. as in boiling cattle that has pressure valve that opens when pressure is too high. if it doesn't work than pressure rises and it could be the reason why that sensor was showing constant high pressure i know, i need to read more
Yes when we replaced the fuel pump we misplaced the wirin for that sensor and we never noticed it. We had a bad maf sensor and thought that was giving us all the codes. Then we shine a light at the tank and see its gone lol. A forum member is sending me a harness he had so I should be good to go!
