E0152-00-Coolant Temp / Fuel Filt Valid Above Normal (B.50.A.95.90
- G.30.C.22)
E0152-00 - Coolant Temp / Fuel Filt Valid Above Normal
Cause:
The coolant temperature is > 115 °C. (NH7.5L Mechanical Engines Only)
Possible failure modes:
1. The coolant temperature sensor B-31 reports that the coolant temperature is above acceptable limits - this is
normal operation of the circuit and indicates a cooling system failure.
2. Coolant temperature sensor B-31 failure.
Solution:
1. The presence of this fault code indicates the engine coolant has exceeded 115 °C. This is not a failure to be
diagnosed electrically unless the sensor is faulty.
A. Locate and repair the mechanical fault in the cooling system.
B. If no cooling system fault can be found, replace the coolant temperature sensor B-31. Continue trou-
bleshooting with Step 2.
2. Visually inspect the harness and connectors for damage, bent or dislocated pins, broken or pinched wires.
A. Repair any damage found during visual inspection.
B. If no damage is found, erase the fault code and continue operation.
