Code 13: Engine Temperature Sensor Circuit

[ElementalFiend]

I've searched and the only thread I could find related to this code wasn't answered.

I just checked my ECU expecting a mass air flow code because of the way the car bogs out at around 4kRPM, but instead I get a code 13. Google and searching here have turned up no results so I'm not really sure what the code is saying the problem is or how to fix it.

Is this related to the way the car bogs under throttle at 4 to 4.5k RPM?

Please someone enlighten me.

I think that your EGR delete is causing that code, considering that code only happens on California cars. And they have much stricter emissions standards. I dunno how to fix that on a California car though.

are you turbo? or n/a?

i ran through the same problem and searched.and found out it is most likely the Distributor.but im still running the same distributor and waiting til i get time to head to the junk yard

PROBLEM:i was running my stock 270cc on my ka-t and it was giving problems til i replace them with my 450cc and it ran fine (untuned)

i also replace the CTS but then it wasnt that. so i wouldnt even bother switching it.

The code-13 is caused by a malfunctioning engine temperature sensor circuit; this is the temperature sensor for the ECU. The sensor itself may be bad or the wiring which will cause the ECU to run a very rich mixture. This will give driveability problems as well as bad MPG.

Judging from the vin number (all match) this isn't a California car.

The car is n/a, completely stock.

Is the sensor located on the ECU or elsewhere? is there any info out there on how to repair/replace the sensor? I'm still not having any luck searching here or elsewhere for the solution.

Since its not a cali car, rogo man is probably right. stick with him

there is an 1989 fsm in my signature. look up coolant temp sensor in my tutorial link in signature also. it is for 91 and i think you sensor might be located in different spot but testing should be the same.

for the CTS, on my 91 KA24DE it was located around my thermostat.the plug was small about 1 inch big and the color was redbut then dont know aobut the single heads

hope this helps if not then

I appreciate the help. The tutorial is a bit vague for me, seeing as how this is my first DIY project car. When it says to "be sure and bleed the coolant system" after testing, what exactly does that mean I should do? Sounds important and I don't want to screw anything up.

Ignore the bleeding part. Im not sure if your sensor has two or one prong. if it has two prongs, you measure ohms between prongs. if only one prong, you measure between prong and engine chasis(ground)

Okay gotcha. Thanks for the help. I'll post here if I screw anything up or all is well with the sensor.
