April 5, 2026: LEMON Manuals is launched! Read the announcement.

DTC C0210/33 Rear Speed Sensor RH Circuit; DTC C0215/34 Rear Speed Sensor LH Circuit; DTC C1273/73 Low Output Signal of Rear Speed Sensor RH (Test Mode DTC); DTC C1274/74 Low Output Signal of Rear Speed Sensor LH (Test Mode DTC): Description

Refer to DTC C0200/31 and C0205/32 (see DTC C0200/31 FRONT SPEED SENSOR RH CIRCUIT; DTC C0205/32 FRONT SPEED SENSOR LH CIRCUIT; DTC C1271/71 LOW OUTPUT SIGNAL OF FRONT SPEED SENSOR RH (TEST MODE DTC); DTC C1272/72 LOW OUTPUT SIGNAL OF FRONT SPEED SENSOR LH (TEST MODE DTC)  ).

DTCs C1273/73 and C1274/74 are cleared when the speed sensor sends a vehicle speed signal or test mode ends. DTCs C1273/73 and C1274/74 are output only in test mode.
