I pulled codes today but im left a bit stumped. I have a rear o2 out which is easy enough. The 3 other codes are
p1335 - CPS related problem(i have no starting issues, my starter was just replaced)
p0440 - EVAP problem???
p0335 - CPS(again makes no sense, car starts fine. Cps was replaced about 2 years ago.)

Like i said the o2 is an easy fix i have done before. But the main stumpers are p1335 and p0440. I dont know anything about evap and i dont know why it thinks my cps is bad when it cant be.

did you try searching to see what other person did when they had these codes.?

Yeh tried searching, as for the cps everything i read says the car wont start when its bad. Yet my car runs fine. Problem is i need an inspection to re register the car and cant with this light on.

check and clean crankshaft sensor. it will take you like 2 mins. as for the evap situation have you driven with a crooked gas cap recently. i know on my dads mazda(dont even get me started) it brought up that same code. also check for any kinked hoses going to and from the evap

try those out reset ecu

Well for the cps i dont know which one i should be looking at. In the fsm diagrams(courtesy of nycmaximas.org) i see 2 things labled cps. One is REF the other POS. Then again i could just try both.

As for EVAP, i know my gas cap has a good seal. I hear it when i open the cap, that soda bottle type of sound. So im thinking its a line or the valve but i might have to have someone do a smoke test. I wonder if those dyes you buy at autozone can work. If so where do i go about adding the stuff.

dont know about the dyes, but IIRC it is somewhere on the org. Try cleaning both REF and POS for the cps. Is anything at all on the car htat isnt running as how it shud.?

Not really. Only real problem perse is a little vibration as if the rpms were dropping at idle. Like once every 5 seconds you get this little vibration felt in the seats but the rpms dont drop, it just vibrates.

Also unrelated, but maybe you all have an answer; when my clutch is pushed in the car is very quiet. But if i put it in neutral and let out the clutch there is this vaccuum noise. Thats the best i can describe it.

if you have a evap code you may have a vac leak. have you done any under the hood work lately?

97maximaman

Well i've had the code for about 6 months, im just lazy. But as far as under hood work since it came on....not really. Cleaned the TB and IACV but i already checked the hoses going to the airbox trap thing. Im not too familiar with vaccuum lines so i dont know where else to look.

my cel came on for the evap system bc of my FTSB i put on. It barely cleared my purge cut valve (canister that sits above the IM on the driver side) and i guess i took some turns too sharply and it cracked one of the plastic valves coming off of the canister. Its a quick check and i guess a possibility if u have a FTSB installed.
