RE5F22A (AW55-50SN)Failsafe No Transmission Codes
2004 and up Nissan Maxima, Quest or 2005 and up Altima with an RE5F22A Asian Warner fi ve speed transaxle in failsafe. The check engine light is on with no transmission codes stored. There is no access to transmission scan tool data available on some after market scan tools. Engine code P0340 Camshaft Position Sensor (Phase) Circuit Bank 1, P0345 Camshaft Position Sensor (Phase) Circuit Bank 2 and/or P0335 Crankshaft Position sensor may be stored. The Camshaft Positionsensors locations are shown in fi gures 1 and 2. The Crankshaft Position sensor is shown in fi gure 3. Any one of these sensors will place the transmission in failsafe.

The only other symptom may be a hard start condition when warm ok cold, caused by a failing Camshaft Position Sensor. An engine surge or misfi re with the tachometer fl uctuating 200-300 rpm is caused by a problem with the Crankshaft Position sensor. Nissan technical service bulletin (TSB) # NTB04-063 refers to problems with both camshaft position sensors but no information about placing the transmission into failsafe.

All three sensors are three wire Hall Effect type and share the same power feed from the ECM relay (fi gures 3, 4 & 5). The ground for all three sensors is shown in fi gure 6. The Crankshaft Position sensor because of its location (bottom center of transmission bell housing) may be subject to connec-tion or wiring problems caused by oil leaks. One other problem that can occur is during transmission removal the crankshaft position sensor hole being used to pry the converter away from the fl ywheel (fi gure 7). This procedure may bend the fl ywheel causing the sensor signal to become erratic also placing the transmission into failsafe mode.
