#12 of 74 Check engine light-Code PO455
Jan 14, 2007 (6:40 pm)
My check engine light on my 2000 Mazda MPV with 86,000 miles has been on for about two years (so probably since around 60,000 miles) with no noticeable problems. I recently failed a vehicle emissions test due to the cel being on and showing code PO455- meaning a large fuel vapor leak. The emissions tester recommended replacing the gas cap, so I took it to an auto parts store, replaced the cap, and they reset the code. Well the cel disappeared for about 3 days and has now come back on after about 200 miles. Does anyone have any idea where to start fixing this problem? Also, I was told I shouldn't go back for an emissions test after the light had been reset until I had driven for at least 500 miles, is that true or could I have taken it back before the light came back on again, and possibly passed emissions or would the code still have shown up?

There is a TSB for p0455 (that's zero four five five, not the letter O) that mentions a wiring harness as a possible cause. And yes, if you went back to the test, they would have been able to determine you cleared the code and that can be grounds for failure on the test.
Even with no noticeable problems, your engine and emissions equipment may be getting damaged by ignoring the CEL for 2 years. You should get it checked out by a dealer or reputable shop. Don't ignore the CEL, if anything at least find out the code and search the 'net, but don't ignore it for 2 years!
#14 of 74 Mazda Engine Light P0455
Jul 19, 2007 (5:02 pm)
Mazda Millenia 2002 2.5L I went to A zone, he read it was two things, and showed me P 0 455. Spark plug mis fire hole 2, and Emissions leak (Large). I bought a spark plug, and changed it. It was old, and worn out, so I am going to do all 6 now. It is either that or a S Plug Wire.
The second part...should I just go to Firestone and ask them to replace all the large hoses that are related to air flow? Or, is it narrowed down to a hose or two and I should just do it myself? What do you think? I have to buy a Hanes for it, or Chiltons...don't have an engine diagram to show where the right hoses are.
If you know that is only one or two hoses, and where they are, can you help me?
Thank you very much.

I'm little confused about how many parts are connected to the engine light? I have a 2002 mazda mpv and already changed and fixed the sensor, coil, converter, cylinder 2, 3, gasket, and other little parts. The light is on and now we a jolt when the gas paddle is press hard. We also fail the inspection, due to code P0037 (emission problem will be cover by Mazda)but the dealership is said it is the P02404 problem ($1,000 to fix). The frustrating parts is the time and money spend in the dealership. Does anyone know if the engine light misfire is a recall. Is the 2002 model a defect?

Our 2001 mpv had smoke coming from the steering column, followed by the headlights only working on high beam. We took it to the dealership, who told us it would be around $500. They then changed their minds and said the harness is melted and it will be around $3000, and they will be happy to sell us a new vehicle, as we would surely not want to put that much money into our old, paid-for van. Had anybody else had this issue?
We had been advised that our insurance might cover this, and after contacting them were told they would cover the repair as well as a rental. They contacted the car rental place and authorized the rental, but have since said they wouldn't cover either one. Does anybody have any advice?

Don't know. But, I may try for a second opinion... maybe from a shop that specializes in electrical. I would sure want to know why the harness melted before putting in another one though. Don't know why your car insurance said they would cover it... it didn't catch on fire.

#21 of 74 Headlights Turn On For no Rreason
Apr 17, 2008 (8:00 pm)
I have a 1994 MPV. 4WD 3.0 V6 W/Lockers. Two questions: 1) Anyone have an idea why after I turn the MPV off the lights come on about 1 minute later? They stay on for about 30 seconds and then turn off again. Then a couple minutes later on they go again. This continues until the battery dies OR!!! I flip the headlight control into highbeam? Any ideas??
2) I have what appears to be a factory sticker that says "CODE ALARM" on both front door windows. Is that a stock Mazda alarm system? I bought the MPV used and didn't get any key fobs with it so I'm not even sure if it has keyless entry.
