Output Speed Sensor Circuit No Signal

Output speed sensor no-signal on the 6L80E is commonly caused by a sheared sensor drive gear or broken reluctor ring inside the tail housing. The sensor itself is on the rear of the transmission near the output shaft. Check for metal shavings in the fluid -- if present, the reluctor ring has broken and you'll need to drop the tail housing to replace it. Otherwise just replace the sensor (AC Delco). Confirm the exact part for your year and engine with a retailer's fitment lookup or your VIN before ordering - these applications split by engine and build date.

Nissan CVT output speed sensor (also called vehicle speed sensor) fails when metal particles from the steel belt contaminate the sensor. Located on the transaxle case near the differential. Pull the sensor and check for metallic buildup on the tip. If CVT fluid is dark or smells burnt, the transmission may have internal damage beyond just the sensor. Replace sensor and do a full CVT fluid exchange using the genuine Nissan fluid your year specifies -- NS-2 on earlier units, NS-3 from roughly the early 2010s -- and nothing aftermarket.

The 6R80 output shaft speed sensor is located on the rear of the transmission. No-signal faults are often wiring related -- the harness runs near the catalytic converter and heat can melt the insulation. Inspect the harness from the sensor connector back to the main transmission plug for heat damage. If wiring is intact, replace the sensor (Motorcraft). Your dealer can confirm whether an open service bulletin or warranty extension applies to your VIN. Confirm the exact part for your year and engine with a retailer's fitment lookup or your VIN before ordering - these applications split by engine and build date.
