MONITOR DESCRIPTION

If there are no signals from the crankshaft sensor even though the engine is revolving, the ECM interprets
this as a malfunction of the sensor.

INSPECTION PROCEDURE

HINT:

Read freeze frame data using the hand–held tester. Freeze frame records the engine conditions when
a malfunction is detected. When troubleshooting it is useful for determining whether the vehicle was
running or stopped. the engine was warmed up or not, the air–fuel ratio lean or rich, etc. at the time
of the malfunction.

READ VALUE ON HAND–HELD TESTER

(a)

Connect the hand–held tester to the DLC3.

(b)

Start the engine and push the hand–held tester tool main switch ON.

(c)

When using hand–held tester, enter the following menu: ”DIAGNOSIS / ENHANCED OBD II / DATA
LIST / ALL / ENGINE SPD”.

The engine speed can be confirmed in DATA LIST using the hand–held tester. If there are no NE sig-
nals from the crankshaft position sensor despite the engine revolving, the engine speed will be indi-
cated as zero. If voltage output of the crankshaft position sensor is insufficient, the engine speed will
be indicated as lower RPM (than the actual RPM).

Check resistance of crankshaft position sensor.

PREPARATION:
Disconnect the C2 crankshaft position sensor connector.
CHECK:
Measure the resistance between terminals 1 and 2.
