Chery Tiggo. Manual - part 82

CHECK CMP SENSOR RESISTANCE

• Check resistance between the following CMP sensor terminals, component side:

TERMINAL NO.

RESISTANCE

⍀

(25°C)

1 & 2

Except 0 or

⬁

1 & 3

2 & 3

Is the check result normal?

Yes

Replace the CMP sensor with a known good CMP sensor.
Monitor the CMP sensor signal on the KES-200 screen.
− If the CMP sensor signals were normal, the system is OK.
− If the CMP sensor signals were still irregular or missing, go to step 13.

Replace CMP sensor.

DIAGNOSIS & TESTING

10.

CHECK CKP SENSOR SIGNAL WAVE PATTERN

• Check signal between CKP sensor (1) terminal 1

and ground, terminal 2 and ground when engine is
running.

ENGINE ANALYZER (KES-200)

CKP SENSOR SIGNAL

Is the CKP output signal normal?

Yes

Go to step 16.

Go to the next step.

11.

CHECK CKP SENSOR

• Remove the CKP sensor (1).

• Inspect and clean the CKP sensor and mounting

area for any condition that would result in an incor-
rect signal, such as damage, foreign material, or
excessive movement.

Is the sensor mounting area OK?

Yes

Go to the next step.

Repair or replace the sensor as

necessary.

12.

CHECK CKP SENSOR RESISTANCE

• Check the resistance of the CKP sensor, component side.

TERMINAL NO.

RESISTANCE

⍀

(25°C)

1 & 2

Approximately 1000

⍀

Is the check result normal?

Yes

Replace the CKP sensor with a known good CKP sensor.
Monitor the CKP sensor signal on the KES-200 screen.
− If the CKP sensor signals were normal, the system is OK.
− If the CKP sensor signals were still irregular or missing, go to step 14.

Replace CKP sensor.

13.

CHECK THE CAMSHAFT AND CAMSHAFT SIGNAL PLATE

• Remove the cylinder head cover and timing belt cover (See Timing Belt Removal & Installation in Section 02

Engine).

• Check the installed clearance (See CMP Sensor Removal & Installation in Section 03 Electronic Engine Con-

trols).

• 0.8 - 1.2 mm should exist.

• Check the camshaft and camshaft signal plate for any condition that would result in an incorrect signal, such as

damage, become flexible, foreign material when rotate the camshaft.

Were any problems found?

Yes

Remove debris and clean the signal plate of camshaft rear end or replace camshaft.
Reinstall CMP sensor.

Go to step 16.

14.

CHECK THE CRANKSHAFT AND CRANKSHAFT SIGNAL PLATE

• Check the installed clearance (See CKP Sensor Removal & Installation in Section 08 Transaxle & Transfer

Case).

• 0.8 - 1.2 mm should exist.

• Check the crankshaft and crankshaft signal plate for any condition that would result in an incorrect signal, such

as damage, become flexible, foreign material when rotate the crankshaft.

Were any problems found?

Yes

Remove debris and clean the signal plate of crankshaft rear end or replace crankshaft.
Reinstall the CKP sensor.

Go to the next step.

15.

CHECK THE TIMING

• Check the timing for misalignment.

Is the timing misaligned?

Yes

Align the engine timing belt (See Timing Belt Removal & Installation in Section 02 Engine).

Go to the next step.

16.

CHECK DTC

• With the X-431 scan tool, read ECM DTCs.

• Refer to ⬙DTC Confirmation Procedure⬙.

Is DTC P0016 still present?

Yes

Replace the ECM.

NOTE : The Immobilizer control module must be matched to the new ECM (See ECM Removal & Instal-

lation in Section 03 Electronic Engine Controls).

The system is now operating properly.
Reassemble the vehicle and road test to verify the customers complaint is repaired.
