Diagnostic Fault Information
Circuit/System Description
The generator control module temperature sensor is a variable resistor that measures the temperature of the coolant entering the generator control
module coolant radiator. The engine control module (ECM) supplies 5 V to the generator control module temperature signal circuit, and a ground
for the generator control module temperature low reference circuit.
Conditions for Running the DTC
P0A01
* DTCs P0112, P0113, P0117, P0118, P0101, P0102, P0103, P0A02, P0A03 and P2610 are not set.
* The ignition has been OFF for greater than 8 hours.
* The temperature difference between the intake air temperature and engine coolant temperature sensors is less than or equal to 16锟斤拷C (60.8锟斤拷F)
at ignition ON.
P0A02
* DTCs P0112 or P0113 are not set.
* The engine is running for greater than 10 seconds.
* The intake air temperature is greater than 70锟斤拷C (158锟斤拷F).
* This DTC runs continuously when the above conditions are met.
P0A03
* DTCs P0112 or P0113 are not set.
* The engine is running for greater than 10 seconds.
* The intake air temperature is greater than -20锟斤拷C (-4锟斤拷F).
* This DTC runs continuously when the above conditions are met.
Conditions for Setting the DTC
P0A01
The engine control module detects that the temperature difference between the generator control module temperature sensor parameter and the
engine coolant temperature sensor is greater than 30锟斤拷C (86锟斤拷F).
P0A02
The engine control module detects that the generator control module temperature sensor parameter is less than -60.5锟斤拷C (-76.9锟斤拷F).
P0A03
The engine control module detects that the generator control module temperature sensor parameter is greater than 162锟斤拷C (323.6锟斤拷F).
