Rear Speed Sensor RH Malfunction (C1403,C1404)
DESCRIPTION
The speed sensor detects wheel speed and sends the appropriate signals to the
skid control ECU (brake actuator assembly). These signals are used for brake control.
The speed sensor rotors have rows of alternating N and S magnetic poles and their
magnetic fields change when the roto ...
Transmission Fluid Temperature Sensor "B" Circuit Short to Ground (P274011)
DESCRIPTION
The No. 2 ATF temperature sensor is installed in the transmission valve body
assembly.
If the ECM detects an abnormally high ATF temperature near this sensor, it illuminates
the warning indicator.
HINT:
The temperature of ATF easily rises when towing, climbing hills, in
