FAULT MESSAGE Engine Water Temperature Sensor Faulty

RESTRICTIONS

Warning only.

ALARM BELL

RESET LEVEL

Medium, Manual
If the fault condition is still present when cleared manually, the fault
will be generated again.

FAULT
RECOVERY

Automatic when the Engine Water Temperature sensor EWT is detected
normal working.

PROBABLE
CAUSES

1.  Engine Water Temperature sensor EWT faulty.
2.  Defective cables
3.  Defective ADB3
4.  Defective MAIP8_EP card in slot 7.

FAULT
ISOLATION

1. Remove the cable connector at the sensor.
2. Measure voltage between pin B & A of the cable connector. The

voltage should be 24V with pin A positive. (+24V)

3. Measure voltage between pin B & C of the cable connector. The

voltage should be 24V with pin B positive. (-24V)

4. If any of the above voltages (+24V) or (-24V) is zero / less:

A. Remove sensor cable connector on ADB3 with cable ID: Z.
B. Measure voltages between pins A, B and C of the ADB3

connector.

a) If voltage between B & A is less than +24V or voltage

between B & C is less than -24V, ADB3 is defective. Replace
the ADB1.

b) If the voltages between pins B&A is +24V and voltage

between pins B & C is –24V, the interconnecting cable
between ADB and sensor with cable ID: Z is defective.

5. If +24V and –24V supply is available at the sensor cable connector,

A. Sensor may be defective. Replace and check.
B. The 19 pin connectors between ADB1 and MEP-660 control unit

with cable ID: AA may be slack. Check and tighten the
connectors.

C. The cable with ID: AA may be defective. Replace the cable and

check up.

D. MAIP8_EP card might be defective. Replace the card and check

up.
