VEHICLE SPEED SENSOR MTR

VEHICLE SPEED SENSOR MTRPFP:24814
DescriptionBCS0010M
Vehicle speed sensor·MTR is built into speedometer assembly. Sensor functions is an auxiliary device to the
revolution sensor when it is malfunctioning. TCM will then use a signal sent from vehicle speed sensor·MTR.

On Board Diagnosis LogicBCS0010O
Diagnostic trouble code “VHCL SPEED SEN-MTR” with CONSULT-II or 2nd judgement flicker without CON-
SULT-II is detected when TCM does not receive the proper voltage signal from the sensor.
Possible CauseBCS0010P

Harness or connector
(Sensor circuit is open or shorted.)

TORQUE CONVERTER CLUTCH SOLENOID VALVEPFP:31940
DescriptionBCS0011O
Torque converter clutch solenoid valve is activated, with the gear in D4 , D3 and 33 , by TCM in response to
signals sent from vehicle speed and the ECM (throttle opening). Lock-up piston operation will then be con-
trolled.
Lock-up operation, however, is prohibited when A/T fluid temperature is too low.
When the accelerator pedal is depressed (less than 2.0/8) in lock-up condition, the engine speed should not
change abruptly. If there is a big jump in engine speed, there is no lock-up.
CONSULT-II Reference ValueBCS0011P
