i have a 1998 oldsmobile intrigue and i have 2 codes showing up left front wheel sensor codes c1225,c1232 i check the harness and looks good i ohm out the sensor and it feel into specs and check the ac out put of the sensor and it was over 100mlv so any help would be great thanks

Clear the trouble codes. Drive the vehicle. Which one comes back? If you have a scan tool that can access the ABS controller, look at the LF wheel speed PID and see what it is reading while driving above 3 mph. Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Those tests really don't rule anything out. I have see a number of problems with the harnesses that are impossible to verify visually. It can also be an issue with the wheel bearing or tone ring. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

I agree. I would pursue the circuit code, if it comes back, first because that is indicating the EBCM is detecting an open or short in the wheel speed sensor circuit. The EBCM actually sends a small amount of voltage through the circuit to test the intrigrity of the circuit. You can use that voltage to troubleshoot the circuit. Another thing that people forget to check is the terminal tension in the connectors. People shove test leads into the terminals can bend the tangs causing a connection problem. Often times you'll run into problems with the harness breaking inside. Sometimes the insulation can get tiny cracks from age and moisture can cause issues. That's why sometimes they have you spray a salty water solution to find problems. Salt makes water more conductive. Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

i pealed the harness back and i look good to me took the rotor off and i didnt see any thing bent broken or any thing that look bad to me any way the the scaner i have is a innova 3160 i should of went for the better scaner but i cheeped out it will not check speed sensors any were eles i can check thanks

Watch this vid. Danner shows a good way to check circuit integrity. http://www.youtube.com/watch?v=bPdPhGcZOe0 Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

ok i did what the vid did and no problem but i am not getting more than 5 v to the sensor its 4.35 and when i plug it into the sensor it only reads 0.18v so i went and got a better scaner that can read all 4 wheel sensors and they all read the same but if you turn the car off and start it again no lights and the scaner shows abs relay on but the second you put it in gear the lights come back on and the scaner shows abs relay off any help would be graet thanks

If you read around 4.0-5.0 volts of bias and it goes to 0 volts when you plug the abs sensor in, you have a short to ground. It is either in the sensor itself or the wiring going back to the EBCM. I would use an ohm meter to make sure your ABS sensor isn't shorted internally to ground. Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

ok so i ohm out the wheel sensor to ground and see if i gives me a reading if i put the meter on eather one of the wheel sensor pins and it show 000 on the meter that means the wheel sensor is going to ground

Right. If you touch the housing with one lead and either pin with the other lead it is shows continuity you have a short to ground. Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
