Speed Sensor Circuit/MTR
WARNING: This page is about a different car, the 2002 Nissan Sentra, 2002 Infiniti G20, 2001 Nissan Sentra, and 2001 Infiniti G20. However, it is still accessible from the selected car via links, so may be relevant.
Using DVOM, backprobe TCM connector. Measure voltage between ground and terminal No. 40 while driving 1-2 MPH for 3 feet or more. See Figure. Voltage should vary from 0-5 volts. If voltage is not as specified, check for continuity in circuit between TCM and speed sensor. Inspect ground circuit. See appropriate INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT.
