Nissan Repair: ect sensor on 2002 altima, 2002 nissan altima, crank shaft


Question
I am having a difficult locating the ect sensor and the tcm speed sensor on my 2002 nissan altima can you help me with this I have a fault code of a PO725 and a P0118 I have already changed my crank shaft positioning sensor.

Answer
Hi Timothy

According to my chart, the P0118 is coolant temp sensor high input and P0725 is speed input circuit malfunction.

Are you have any driveability problems?

If not, I would reset the codes and see if they return. They may be nuisance codes.

If you need to replace, the speed sensor is located in the transmission, near the input for the speedo cable. The coolant sensor should be near the thermostat housing outlet.

Don't know if you have a 6 cyl or 4 cyl, so this is my best guess on locations.

Hope this helps -
