DESCRIPTION
Factors that affect the indicated vehicle speed include tire size, tire inflation, and tire wear. The speed indicated on the speedometer has an allowable margin of error. This can be tested using a speedometer tester (calibrated chassis dynamometer). For details about testing and the margin of error, see the reference chart.

INSPECTION PROCEDURE
NOTICE: If the vehicle speed is outside the allowable range when tested, perform the following procedure.
1 PERFORM ACTIVE TEST BY INTELLIGENT TESTER
METER:
*1: for U.S.A.
*2: Except for U.S.A.
OK: Needle indication is within the allowable range.
2 READ VALUE OF INTELLIGENT TESTER
METER:
OK: Vehicle speed displayed on the tester is almost the same as the actual vehicle speed measured using a speedometer tester (calibrated chassis dynamometer).
REPLACE COMBINATION METER ASSEMBLY
3 READ VALUE OF INTELLIGENT TESTER
ABS/TRAC/VSC:
OK: Vehicle speed displayed on the tester is almost the same as the actual vehicle speed measured using a speedometer tester (calibrated chassis dynamometer).
4 INSPECT COMBINATION METER ASSEMBLY
Standard voltage
*1: without VSC
*2: with VSC
Result
5 INSPECT COMBINATION METER ASSEMBLY
OK: The waveform is displayed as shown in the illustration.
HINT: As the vehicle speed increases, the cycle of the signal waveform narrows.
Result
REPLACE COMBINATION METER ASSEMBLY
6 CHECK HARNESS AND CONNECTOR (COMBINATION METER - BRAKE ACTUATOR ASSEMBLY)
Standard resistance
REPLACE COMBINATION METER ASSEMBLY
7 CHECK HARNESS AND CONNECTOR (COMBINATION METER - ABS & TRACTION ACTUATOR ASSEMBLY)
Standard resistance
REPLACE COMBINATION METER ASSEMBLY
Installation
1. INSTALL FRONT SEAT ASSEMBLY LH
Place the seat assembly in the cabin.
NOTICE:
Be careful not to damage the body.
Connect the connectors under the seat assembly.
Tighten the 2 bolts on the front side of the seat
assembly.

Transmission Fluid Temperature Sensor "A"
DESCRIPTION
The ATF (Automatic Transmission Fluid) temperature sensor converts the fluid
temperature into a
resistance value which is input into the ECM.
The ECM applies a voltage to the temperature sensor through ECM terminal THO1.
The sensor resistance changes with the transmission f ...
Engine Coolant Temperature Circuit Range / Performance Problem
DESCRIPTION
Refer to DTC P0115 (See page ES-133).
MONITOR DESCRIPTION
The ECT sensor is used to monitor the ECT. The ECT sensor has a built-in
thermistor with a resistance
that varies according to the temperature of the engine coolant. When the ECT
becomes low, the
resistance of the ...
