MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-445

DTC P0335: Crankshaft Position Sensor Circuit

.

CIRCUIT OPERATION

• The crankshaft position sensor power is supplied

from the ECM (terminal No. 9).

• Terminal No. 2 of the crankshaft position sensor

is grounded with ECM (terminal No. 24).

• A 5-volt voltage is applied on the crankshaft posi-

tion sensor output terminal (terminal No. 3) from
the ECM (terminal No. 8). The crankshaft position
sensor generates a pulse signal when the output
terminal is opened and grounded.

MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-446

TECHNICAL DESCRIPTION

• The crankshaft position sensor detects the crank

angle (position) of each cylinder, and converts
that data to pulse signals, then which are input to
the ECM.

• When the engine is running, the crankshaft posi-

tion sensor outputs a pulse signal.

• The ECM checks whether pulse signal is input

while the engine is cranking.

.

DESCRIPTIONS OF MONITOR METHODS

• Crankshaft position sensor signal does not

change.

• Crankshaft position sensor signal is not normal

pattern.

.

MONITOR EXECUTION

Continuous

Check Condition

• Engine is being cranked.

• Engine speed is higher than 500 r/min excluding

during cranking.

Judgement Criterion

• Normal signal pattern has not been input for cyl-

inder identification from the crankshaft position
sensor signal and camshaft position sensor sig-
nal for 2 seconds.

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-448

STEP 1. Using scan tool MB991958, check data list item 2:
Crankshaft Position Sensor.

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 to the data link connector.
(2) Start the engine and run at idle.
(3) Set scan tool MB991958 to the data reading mode for item

2, Crankshaft Position Sensor.

• The tachometer and engine speed indicated on the scan

tool should match.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the sensor operating properly?

YES : It can be assumed that this malfunction is intermittent.

Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points

− How to

Cope with Intermittent Malfunctions

P.00-15

.

NO : Go to Step 2.

STEP 2. Check harness connector B-119 at the crankshaft
position and harness connector B-10 at ECM for damage.
Q: Is the harness connector in good condition?

YES : Go to Step 3.
NO : Repair it. Refer to GROUP 00E, Harness Connector

Inspection

P.00E-2

. Then go to Step 9.

STEP 3. Measure the sensor supply voltage at crankshaft
position sensor harness side connector B-119.
(1) Disconnect the connector B-119 and measure at the

harness side.

(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 1 and ground.

• Voltage should be battery positive voltage.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is battery positive voltage (approximately 12 volts)

present?
YES : Go to Step 6.
NO : Go to Step 4.
