5. ECT sensor 1 inspection
-1. Connect the ECM connector A and the ECT sensor
1 connector.
-2. Turn the ignition switch ON and check the engine
temperature with the HDS (Dr. H or Pocket Tester).
◆
Does it agree with actual engine temperature?
YES - Recheck with a new ECM.
NO -
Replace the ECT sensor 1.

TP (Throttle Position) Sensor
DTC 7-1: Low TP sensor voltage
1. Reappearance test
-1. Connect the HDS (Dr. H or Pocket Tester) (page 5-
1) and clear the DTC (page 5-2).
• If the DTC cannot be cleared, continue trou-
bleshooting.
-2. Turn the ignition switch ON.
-3. Check the TP sensor voltage with the HDS (Dr. H or
Pocket Tester).
◆
Is there 0.098 ~ 4.922 V?
YES - Temporary failure (Disappears).
NO -
Go to the step 2.
2. TP sensor power (VCC1) circuit inspection
-1. Turn the ignition switch OFF and disconnect the TP
sensor connector.
-2. Turn the ignition switch ON.
-3. Measure the voltage between the No. 1 (Brown/
) and No. 3 (Green -) terminals of the TP
sensor wire harness side 3P connector.
◆
Is there 4.75 ~ 5.25 V?
YES - Go to the step 4.
NO -
