Temp Coolant sensor -cel light

Hi

I recently got a cel in my 01 gs430,which was for the temp coolant sensor,so i replace it and the same code is appearing again.

Has anyone had this problem before?

Thanks in advance for your help

what was the code that was pulled? That could help you. There are other factors that could be involved too.

Call wherever you got the code read and the part replaced and get the exact code from them. Better to be sure then to guess. If you got a receipt for the diagnostic they generally will list it there.

That said it sounds like a P0115 to me. This list code specifies the Coolant Sensor, the Coolant Sensor circuit, or the ECM (rare).

No codes ever specify to 'replace' anything. They are just a basis to troubleshoot from.

Just like any code that ever has anything to do with O2 the autozone guys just tell you to replace all the O2 sensors in the car that's got to be it. The ecu will throw O2 codes for a multitude of reasons when the readings are out of range and it could be due to other factors like injectors or maf problems casuing improper mixture going in hence improper burn coming out or cat issues for the rear o2's..

Same principal applies, you need the exact code again to see what the possible causes are.

HI all

Just to update this thread.

I filled my coolant to full and reset the ecu,the code/cel is gone and has not came on again.

So low coolant will trigger this cel and show code for coolant temp sensor.

Thanks for your help
