DTC P0335 CRANKSHAFT POSISTION SENSOR (TDC)
PFP:23731
DescriptionEBS004RQ
The crankshaft position sensor (TDC) monitors engine speed by
means of signals from the sensing plate (with 23 protrusions)
installed to the fly wheel. The datum signal output is detected 15°
signal and sent to the ECM. The sensor signal is used for fuel injec-
tion control and fuel injection timing control.
CONSULT-II Reference Value in Data Monitor ModeEBS004RR
Specification data are reference values.
ECM Terminals and Reference ValueEBS004RS
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)

DTC Confirmation ProcedureEBS004RU
Before performing the following procedure, confirm that battery voltage is more than 10V.
WITH CONSULT-II
1. Turn ignition switch “ON” and select “DATA MONITOR” mode
with CONSULT-II.
2. Crank engine for at least 1 second.
3. Start engine and run it for at least 2 seconds at idle speed.
4. If DTC is detected, go toEC-737, "
Diagnostic Procedure".

Diagnostic ProcedureEBS004RW
1.CHECK CRANKSHAFT POSITION SENSOR (TDC) GROUND CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch “OFF”.
2. Loosen and retighten engine ground screws.
3. Disconnect crankshaft position sensor (TDC) harness connector
and ECM harness connector.
4. Check harness continuity between ECM terminal B20 and
crankshaft position sensor (TDC) terminal 1. Refer to Wiring
Diagram.
5. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 2.
NG >> Repair open circuit or short to ground or short to power
in harness or connectors.
2.CHECK CRANKSHAFT POSITION SENSOR (TDC) INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Check harness continuity between crankshaft position sensor (TDC) terminal 2 and ECM terminal B21.
Refer to Wiring Diagram.
2. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 3.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
3.CHECK CRANKSHAFT POSITION SENSOR (TDC)
Refer toEC-737, "
Component Inspection".
OK or NG
OK >> GO TO 4.
NG >> Replace crankshaft position sensor (TDC).
4.CHECK INTERMITTENT INCIDENT
Refer toEC-699, "
TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT".

DescriptionEBS008YN
The camshaft position sensor identifies a particular cylinder by
means of signals from the sensing plate (with five protrusions)
installed to the camshaft. The datum signal output is detected 90°
signal and sent to the ECM. The sensor signal is used for fuel injec-
tion control and fuel injection timing control.

Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
