Question about 1996 Mazda Protege

1 Answer

Do I need to replace the crank positioning sensor?

I took my 96 Mazda Protege in for overheating they found the radiator cracked, I had the radiator replaced along with a hose and clamps and a faulty thermostat. The mechanic started the engine and let it run and the engine checks out ok but the check engine stays on I'm being told it's the PO335 crank positoning sensor I was told it would be ok to run the car with the check engine light on without damaging the car. Is this true? And how hard is it to replace this sensor?

    I was told that they really can't tell if it's the sensor because the car is still running. The mechanic told me he doubts the sensor is faulty because the car starts up and runs but the expense involved in repairing the problem if they find the sensor is good is a hefty cost! He also mentioned that if they find the sensor was good there would have to be something wrong with the cars computer does this sound right?

The sensor is not to hard to change takes an experienced mechanic a little less tan an hour if it does not brake. it really doesn't hurt your car to run with a faulty sensor but if the sensor competly craps out your car probably won't start i would get it repaired if i were you so your not stranded some where.

    yes that is possible. it is true that usaully the car does not run with a faulty sensor. if i were you and had an advanced auto or autozone in your area i would go there and use there scan tool and retrieve the codes yourself after driving the car now and see what they say, it is free to use there scan tool and it would give you some more info without having to pay a diagnostic fee. that let me know if there are additional codes or if the crank sensor code is still presesnt.

Mazda protege 5 2003 crank wont start


I purchased a used 2003 Mazda Protege w/170k on it. I knew it had a rod knocking at the time. It was still running. I bought a used motor 35k from Japan. I swapped everything But could never get it to run. I took it to the Mazda dealer (why not just flush cash in the toilet) They lied and said it needed a new computer.
Finally discovered that the harmonic balancer / lower pulley had Japanies spline for the crank position sensor. It ran great after I put the old pully on. In the intake the butterfly valves had come lose and fallen into the intake valves and shredded and then gotten into the crank. If you are hearing rattling remove your intake and you will find the butterfly valves have come loose.

My mazda protege is running hot and the radiator has water


Some thing too check:
Make sure coolant level is up to line and clean (not dirty, do to clogged radiator, may need to be flushed or replaced).
Make sure air flow through the out side of radiator is clear (dirt, leaves, ect..) .
Make sure fan is working properly equip t (is not running too slow). Or Manual (belt driven) fan clutch is working properly, not loose or spinning too freely?
Check for broken or cracked fan blades itself.
Check radiator cap, (no gasket tears).
Could be thermostat going bad ?
Could be coolant temperature Relay or sensor/switch (from computer) going bad?
Check radiator hose(s) (too soft, may collapse)?
In some rare cases:
Timing could be off.
Could be water pump.
Could be blown head gasket(s).
Could have cracked head(s).
ECT..............Hope this was some help???

It just unbolts but I would also clean the mass air flow sensor. This could also cause a TPS code.
