Ok checked the codes and it threw a 41 and a 4. Primary Oxygen sensor and the Crankshaft Position Sensor. Have no idea how to fix or even how they go bad in the first place? Any help and where I can look and if this is an easy fix hopefully. Any guidance would be appreciated. I have a 95 SI btw.

 

Plan on budgeting for a new O2 sensor and a new distributor.

 

Damn. I just replaced the distributor like 3 weeks ago. I would think it is not that but do you have any idea what could have caused this? Im not really to sure why the crankshaft position sensor is jacked.

 

Did you buy an AutoZone lifetime warranty distributor? If yes, take it back and try another one.

If you have a meter, you can measure the O2 heater resistance and compare to spec: 15-40 ohms.

 

Yes, I did buy an autozone lifetime warranty distributor. I do have a meter but can you point me in the right direction. I think I know where the sensor is but im not sure. Do I measure with car on or car off? Also is it ok to drive with this not working?

One more thing is it possible I put the distributor on 180 degrees different? Meaning the shaft where it connects with the motor could that be opposite? I would think the motor would not run at all in that case. Let me know and ill turn it around and see if that makes a difference.

 

Not being a 5th gen guy, I'm not sure if you could put the dizzy 180* out-of-phase. But on the 6th gen's, there is no way - the key is actually offset from center. But if it was 180* out, the engine wouldn't run, or barely at all.

The O2 sensor is going to be the only sensor situated in the exhuast piping - sooo...just go out and look for it. You'll eventually find it sticking out of the exhaust (before the catalytic converter, if you have one) and it has 4 wires.

To measure the O2 heater resistance, disconnect the O2 sensor from the main engine harness. Using the meter, measure the resistance between the two black wires of the connector - 15-40 ohms is spec.

 

Ok just took of my dizzy cap just to check if anything seemed odd. Everything seemed ok. So I put my cap back on and everything looks ok. Started up car again just for the hell of it and no check engine light. At all. So I drove around for a few minutes near bye just in case and nothing. Runs perfect. Im quite confused. I dont want to replace parts I dont have to and unfortunately I cant get my car off the ground right now. Dont have my ramps here. Should I just ignore it? My car will run fine without replacing the o2 sensor right?

 

One more thing. Im wondering if this was the problem. My distributor does not have a dust cap. Is it possible some of the dust got on the sensor in the dizzy? Im wondering if that was the problem. Its possible I suppose.

 

When our engines warm-up, they like to go into a state called "closed loop". Closed loop uses the O2 sensor in order to make fine adjustments to the fuel mixture.

Will your car be OK without one - define OK? If your basically stock, then fix it. Rich mixtures kill catalytic converters, increase deposits and generally lead to rougher running.

For the distributor - your call. I'd return it and get a new one.
