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.
Removal and InstallationEBS011AT

DTC P0335 CKP SENSOR

DTC P0335 CKP SENSORPFP:23731
DescriptionEBS011AU
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 ModeEBS011AV
Specification data are reference values.
ECM Terminals and Reference ValueEBS011AW
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.

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-1047, "
Diagnostic Proce-
dure" .
