#3649 of 3738 Mazda Protege 2002 check engine light on.
Feb 14, 2011 (10:07 am)
I have Mazda Protege 2002 model. i have check engine light. The codes for check engine light are P0300 and P0431 (OEM number). Car is on with check engine light since a month but lately the light have been flashing and car seems to be less powerful. Car shuts down when I stop at traffic light and sometimes gives push. Except getting tune up can some one suggest what has happened?

flashing light is not a good sign. You have a misfire and you are probably (potentially) going to damage your catalytic converter---that's why it's flashing right now.
The cause of misfires are numerous and you have no choice but a step by step diagnosis to eliminate any one of 10+ possible causes.
In any event, you'd better get on this.
Causes might include bad crankshaft positioning sensor, bad camshaft positioning sensor, bad coil, bad high tension lead, MAF sensor, vacuum leaks in intake manifold, fuel pump malfunction, fuel pressure regulator malfunction, clogged fuel filter, evaporative emissions system malfunction, PCV malfunction, EGR malfunction, related vacuum hose or wiring harness defects.

I have had my 92 protege for a few years now, I never drove a standard or evan a used car before... economy. So in any event would like to know how I can check to see if my transmission is leaking.

Mar 09, 2011 (12:26 pm)
I have a 2002 mazdz protege dx I am having problems with a rough idle and missing after the engine reaches operating temp. I replaced the o2 sensors with a exact fit and the idle got worst. the old one was a denso and the new one is bosch. the enging will miss when i put it in gear or or when the rad fan turns on or the ac. if i increase the idle speed with the gas pedel there is no problem and no missing. the check engine light is not on. can anyone help me
thanking you in advance

My 2002 P5 has been run dry and cooked the rings. I found a used FS engine that is reported to be from 97-98 626 or 01-03 Protege.
Can anyone confirm if the same bottom end/ short block will work with both these cars? Should be able to swap accessories and get on the road?
Just to clarify, my P5 gave nearly 300K miles before it was destroyed by a vengfull X spouse.

You'd best identify it more carefully. The part # for a 2001-2003 Protege short block is the same but the 626 is different.
so if it's a 2001-2003 Protege engine, that's good, but you should still plan on running into some problems as there are bound to be differences in wiring, sensors, or perhaps even how things bolt onto the block.
Also don't buy a used engine you can't hear run.

#3657 of 3738 Cooling Fans Non Functional (Normal Operation Mode)
Mar 28, 2011 (10:11 am)
I have a 2000 Mazda Protégé LX 1.6L Engine
The problem is the cooling fans don’t turn on causing the engine to overheat. Here is what I have done so far. (NOTE: Both R/H and L/H fans turn on/off during A/C cycle operation)
1. Replaced temperature sensor (2-wire sensor. Only one sensor in car)
2. Replaced relays with new ones.
3. Removed and checked all applicable fuses under hood
4. Removed and checked water pump. No problems found
5. Flushed Radiator
6.Got rid of engine thermostat
7. No radiator leaks detected
If I remove the temperature sensor harness while the engine is running both fans turns on with A/C switch in OFF position. Then check engine light turns on. I suppose it detects a fault in the circuit and runs on protection mode.
What will be my next step(s) before replacing the ECM?
Any advise would be greatly apprecaited.
