OPERATION

œ

Power is supplied to the crank angle sensor (ter-
minal No. 3) from the engine control relay (termi-
nal No. 1) and is earthed to the engine-ECU
(terminal No. 40) from the crank angle sensor
(terminal No. 1).

œ

A power voltage of 5 V is applied to the crank
angle sensor output terminal (terminal No. 2)
from the engine-ECU (terminal No. 89).

FUNCTION

œ

The crank angle sensor detects the crank angle
(position) and inputs a pulse signal to the engine-
ECU.

œ

In response to the signal, the engine-ECU con-
trols the injector, etc.

TROUBLE JUDGMENT

Check Condition

œ

Engine in cranking state.

Judgment Criterion

œ

The sensor output voltage remains unchanged
(no pulse signal is inputted) for 2 seconds.

PROBABLE CAUSE

œ

Failed crank angle sensor

œ

Open/short circuit in crank angle sensor circuit or
loose connector contact

œ

Failed engine-ECU

DIAGNOSIS PROCEDURE

STEP 1. MUT-II data list

œ

Refer to Data list reference table

).

NO :

Go to Step 2 .

STEP 2. Connector check: B-29 crank angle
sensor connector

Q: Is the check result normal?

YES :

Go to Step 3 .

NO :

Repair.

STEP 3. Measure voltage at B-29 crank angle
sensor connector.

œ

Disconnect connector, and measure at harness
side.

œ

Ignition switch: ON

œ

Voltage between terminal No. 2 and earth.

OK: 4.9

-

5.1 V

Q: Is the check result normal?

YES :

Go to Step 9 .

NO :

Go to Step 4 .

STEP 4. Measure voltage at C-137 engine-ECU
connector.

œ

Measure engine-ECU terminal voltage.

œ

Disconnect B-29 crank angle sensor connector.

œ

Ignition switch: ON

œ

Voltage between terminal No. 89 and earth.

OK: 4.9

-

5.1 V

Q: Is the check result normal?

YES :

Go to Step 5 .

NO :

Go to Step 6 .

STEP 5. Connector check: C-137 engine-ECU
connector

Q: Is the check result normal?

YES :

Check and repair harness between B-29

(terminal No. 2) crank angle sensor
connector and C-137 (terminal No. 89)
engine-ECU connector.

œ

Check output line for open circuit.

NO :

Repair.

STEP 6. Connector check: C-137 engine-ECU
connector

Q: Is the check result normal?

YES :

Go to Step 7 .

NO :

Repair.
