2007 Lucerne CXL ABS problems

[OG Style]

I trying to help fix a car with a abs error and I believe it is a wheel speed sensor. Does anyone know what the resistance should be on the sensors and if there is a place under the hood to test all of them?

Thank you

Thanks. I'm not sure what this is. I'm not getting any error codes using my obd scanner. I only have a cheap scanner.

You were asking what the resistance was on the sensors.

I don't understand the chart. I thought the c0040, c0045 and c0035 were trouble codes.

I checked the resistance on the front wheels with them disconnect. I got about 1.2k ohms on one and the other one was reading around 60k ohms and it kept climbing.

you have to test each one individually

980 to 2,350 ohms is what I found as an acceptable resistance range. The 60K reading is a defective sensor.

Is there a location under the hood where I can check them all? It's hard to get to the rear sensors with the wheel on. Thank you

 

[MelsRegal]

no they are tested at the wheel sensor connector at each wheel

I'll do that. Thank you
