1G Engine codes 11, 13, 15

[Kyra115]

I have the engine codes 11,13, and 15 for my 94 eclipse. Any help for a noobie?

Code 11 is for a fault with the O2 sensor
Code 13 is for a fault with the Intake Air Temp sensor
Code 15 is 1.8L NA specific and is for the Motor Position Sensor.

Do you have a copy of the factory service manuals?

I do not sadly

Also I have already changed the 02 sensor to a new one?

Assuming the replacement sensor was plug and play have you reset the ECU and still see the code? (Resetting the ECU by pulling the room fuse or by disconnecting the battery, for a few seconds.)

Alright I’ll make sure to do that. Also from what I’ve read is the IAT inside the mag reader itself?

 

[steve]

Yes, the IAT sensor is inside the MAF sensor.

Do you know where I can purchase a MAF sensor? I’ve been browsing around and can’t seem to find any.

I'd try measuring the sensor output first per the manual.

Fault code 15 is motor position sensor is embedded within the distributor, so you have not choice, but to fully replace the distributor. This is the 4g37 version of the 4G63's CAS.

Make sure you don't have breaks in the wires from heat.

Alright sounds simple enough. Thank you for helping me out so far! I’m grateful. I’ll keep you posted about what happens.

Changed the distributor and Maf sensor. Car starts up but then starts sputtering then dies. Idle fluctuates and when it gets low enough it just dies. The air inlet hose is pretty well worn but before the change of parts it was working fine. Do you have any tips of what it could be?
