DTC P2135: Throttle / Pedal Position Sensor / Switch “A”/“B” (Main / Sub) Voltage CorrelationS7RS0B1104076
Wiring Diagram9
Ground circuit check
1) Remove ECM from its br acket with ECM connectors
connected.
2) Check for proper connection of ECM connector at “E23- 51” terminal.
3) If OK, measure resistance between “E23-51” terminal of ECM connector and engine ground.
Is resistance below 5
Ω? “WHT” wire is open or
high resistance circuit.
Faulty ECM ground
circuit. If circuit is OK,
substitute a known-
good ECM and recheck.
10 APP sensor check
1) Check APP sensor (sub) re ferring to “APP Sensor
Assembly Inspection in Section 1C”.
Is output voltage within specified value? Substitute a known-
good ECM and recheck.
Replace APP sensor.

Circuit Description
When the ignition switch is turned ON, the main relay turns ON (the contact point closes) and the main power is
supplied to ECM.
Troubleshooting
NOTE
When measuring circuit voltage, resistance and/or pulse signal at ECM connector, connect the special
tool to ECM and/or the ECM connectors referri ng to “Inspection of ECM and Its Circuits”.

StepAction YesNo
1 Circuit fuse check
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Check for proper connection to ECM connector at “E23- 2”, “E23-29”, “E23-60”, “E23-1”, “E23-16”, “E23-31”,
“C37-58”, “C37-15” and “C37-30” terminals.
3) If OK, check “RADIO” fuse and “IG COIL” fuse for blowing.
Are “RADIO” fuse and “IG COIL” fuse in good condition? Go to Step 2.
Replace fuse (s) and
check for short in
circuits connected to
fuse(s).
2 Power supply circuit check
1) Measure voltage between “E23-2” terminal of ECM
connector and body ground.
Is voltage 10 – 14 V? Go to Step 3.
“WHT/RED” or “WHT”
wire is open circuit.
3 Ignition signal check
1) Turn ignition switch to ON position.
2) Measure voltage between “E23-29” terminal of ECM
connector and body ground.
Is voltage 10 – 14 V? Go to Step 4.
“BLK/WHT” or “GRN”
wire is open circuit.
4 Main relay circuit check
1) Turn ignition switch to OFF position.
2) Check “FI” fuse (1) in indivi dual circuit fuse box No.1 for
blowing.
3) If OK, measure voltage between “E23-60” terminal of ECM connector and body ground.
Is voltage 10 – 14 V? Go to Step 5.
Go to Step 9.

MAF and IAT Sensor InspectionS7RS0B1306020
CAUTION!
Do not heat up MAF and IAT sensor more
than 100 °C (212 °F). Otherwise, MAF and IAT
sensor will be damaged.

• Check sensor O-ring (1) for damage and deterioration. Replace as necessary.
• Blow hot air to temperature sensing part (2) of MAF and IAT sensor (3) using hot air drier (4) and measure
resistance between sensor terminals while heating air
gradually.
If measured resistance does not show such
characteristic as shown, replace MAF and IAT sensor.
IAT sensor resistance
–20 °C (–4 °F): 13.6 – 18.4 k Ω
