CHECK TURBOCHAGER BOOST SENSOR INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1.
Check harness continuity between ECM terminal 52 and turbocharger boost sensor terminal 2. Refer to
Wiring Diagram.
2.
Also check harness for short to ground and short to power.
OK or NG
OK
>> GO TO 5.
NG
>> Repair open circuit or short to ground or short to power in harness connectors.

CHECK TURBOCHARGER BOOST SENSOR
Refer to
EC-181, "Component Inspection"
.
OK or NG
OK
>> GO TO 6.
NG
>> Replace turbocharger boost sensor.

CHECK TURBOCHARGER BOOST SENSOR
1.
Remove turbocharger boost sensor with its harness connected.
2.
Turn ignition switch ON.
3.
Use pump to apply pressure sensor as shown in the figure.
CAUTION:
●
Always calibrate the pressure pump gauge when using it.
●
Inspection should be done at room temperature [10-30
°
C (50-86
°
F)].
4.
Check the output voltage between turbocharger boost sensor terminal 2 and body ground.

DTC P0335 CKP SENSOR
DTC P0335 CKP SENSOR
PFP:23731
Description
EBS013NQ
The crankshaft position sensor monitors engine speed by means of
signals from the sensing plate (with 56 protrusions) installed to the
fly wheel. The datum signal output is detected 6
°
signal and sent to
the ECM. The sensor signal is used for fuel injection control and fuel
injection timing control.
CONSULT-II Reference Value in Data Monitor Mode
EBS013NR
Specification data are reference values.
ECM Terminals and Reference Value
EBS013NS
Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
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 Procedure
EBS013NU
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
1.
Turn ignition switch ON.
2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
Start engine and let it idle for at least 5 seconds.
If engine could not start, keep ignition switch at START position
for 5 seconds.
4.
If 1st trip DTC is detected, go to
EC-185, "Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.
DTC No.
