#2325 of 3742 Evaporative Emissions System Leak
Feb 10, 2005 (3:33 pm)
The CEL on my 1997 Mazda Protege recently went on and stayed on. My mechanic diagnozed it as an evaporative emissions system problem (the evaporated gasoline from the fuel tank is meant to be absorbed in a charcoal canister and sucked into the engine through a valve) and wants to replace the canister purge valve. He claims that this part costs $250 dollars and has an electrical component inbuilt into it. I looked at online autopart sites but cant find this part available for this year and model.
Does anyone know whether this sounds like an honest quote? Sounds like robbery to me.

Is this only available as an OEM part or is an aftermarket part possible?
Is the labor extra or included in your quote?
You may want a second quote from a Mazda dealership and/or another garage.
Here is something on the EVAP that I extracted from Haynes' Chilton Guide to the Protege.
Evaporative Emission Control (EVAP) system
The EVAP traps and stores fuel that evaporates from the fuel tank, throttle body and intake manifold that could escape into the atmosphere as hydrocarbon emissions. It consists of a charcoal-filled canister, the lines connecting the canister to the fuel tank, a temperature controlled vacuum valve and a check valve. Fuel vapors are transferred from the fuel tank and throttle body to a canister for storage when the engine isnít running. When the engine is running the vapors are purged from the canister by intake airflow and consumed in normal combustion. The canister is equipped with a check valve that incorporates three check balls. Based on the running conditions and the pressure in the fuel tank, the check balls open and close the passages to the vacuum valve (consequently the throttle body) and fuel tank.

Thanks for the tips...I'll check into it. My mechanic claims there is no aftermarket. Labor not included.
#2328 of 3742 Marshall, here's some interesting reading ...

Interestingly, the following article (which I found very easily by typing "canister purge valve protege" into Google) applies to the 1996-1998 Proteges:
BTW, I just called the parts department at my Mazda dealer and, playing the part of you, asked for a price on a "canister purge valve" for a 1997 Protege.
"Mazda doesn't have anything called a 'canister purge valve' on the 1997 Protege."
Ask this mechanic guy of yours for the real part name, or find another mechanic. Is this guy at a Mazda dealership, btw?

What did the dealers do to fix this issue? I think I have a wiring problem.
Thanks in advance.

Post the specific diagnostic trouble code number. Several codes relate to the EVAP system.

Thanks. Battery, air filter and coolant OK. So is head gasket. Will look towards EGR, injectors and fuel pump.
#2332 of 3742 A few questions
Feb 20, 2005 (6:50 am)
I'm in the market for a used, super reliable sedan. I understand the Protege sedan is no longer made, but from what I've read about it, it sounds like a very reliable car.
Would any of you say it's as well built and reliable as a Civic or Corolla? What was the first year Mazda started putting the 2.0 engine in the Protege? Thanks.
#2333 of 3742 replaced clutch on 94 mazda protege...have a problem
Feb 24, 2005 (10:45 am)
Hi, I have a 94 mazda protege, and I cant wait to get rid of it. Anyways we have put in a new clutch (manual transmission) and have assembled everything however there is a slight problem. When pushing the pedal in it does not feel as if it has enough pressure (has some but not as it should). When I push the pedal in and try to shift, it is tough to get into gear like it binds and I cant get it into reverse...it just grinds. We've bled the system what else to do?

It was a "solenoid valve" in the evaporative emissions system that needed replacing. Checked with a second mechanic -- paid $95 for part and 160 for labor. CEL has stayed off since.
Thanks everyone who responded.
