HINT:

SPD (SP2) is always 0 while driving:

Open or short in the sensor or circuit.

The SPD (SP2) value displayed on the Techstream is much lower than the actual vehicle speed:

Sensor trouble, improper installation, or intermittent connection trouble in the circuit.

PROCEDURE

1.

INSPECT SPEED SENSOR SP2 INSTALLATION

(a) Check the speed sensor SP2 installation.

OK:

The installation bolt is tightened properly and there is no

clearance between the sensor and transmission case.

When the brake pedal is depressed, this switch sends a signal to the ECM. Then the ECM cancels the operation of

the lock-up clutch while braking is in progress.

DTC DETECTION CONDITION

TROUBLE AREA

P0724

The stop light switch remains ON even when the vehicle is driven in a

STOP (less than 3 km/h (1.86 mph)) and GO (30 km/h (18.65 mph) or

more) pattern 5 times. (2-trip detection logic)

signal circuit

Stop light switch

ECM

MONITOR DESCRIPTION

This DTC indicates that the stop light switch remains ON. When the stop light switch remains ON during "stop and

go" driving, the ECM interprets this as a fault in the stop light switch and the MIL comes on and the ECM stores

the DTC. The vehicle must stop (less than 3 km/h (1.86 mph)) and go (30 km/h (18.65 mph) or more) 5 times

for 2 driving cycles in order to detect a malfunction.
