Diagnostic Codes Table
Code Conditions which Generate this Code System Response
100-3 Engine Oil Pressure Sensor : Voltage Above Normal The Electronic Control Module (ECM) has detected a voltage on the sensor's signal wire that is greater than 4.8 volts for 5 seconds. The ECM assumes the last valid value for the suspect sensor. The monitoring of the engine condition by the ECM is disabled. This disables the engine protection for the engine condition.
The fuel is shut off. The shutdown output is activated. The code is logged.
Since the engine protection is disabled, the engine is shut down.
The alarm output is activated.
100-4 Engine Oil Pressure Sensor : Voltage Below Normal The ECM has detected a voltage on the sensor's signal wire that is less than 0.2 volts for 5 seconds.
101-3 Crankcase Air Pressure Sensor : Voltage Above Normal The ECM has detected a voltage on the sensor's signal wire that is greater than 4.5 volts for 5 seconds.
101-4 Crankcase Air Pressure Sensor : Voltage Below Normal The ECM has detected a voltage on the sensor's signal wire that is less than 0.5 volts for 5 seconds.
172-3 Intake Manifold Air Temperature Sensor : Voltage Above Normal The ECM has detected a voltage on the sensor's signal wire that is greater than 4.8 volts for 5 seconds.
172-4 Intake Manifold Air Temperature Sensor : Voltage Below Normal The ECM has detected a voltage on the sensor's signal wire that is less than 0.2 volts for 5 seconds.
174-3 Fuel Temperature Sensor : Voltage Above Normal The ECM has detected a voltage on the sensor's signal wire that is greater than 4.5 volts for 5 seconds.
174-4 Fuel Temperature Sensor : Voltage Below Normal The ECM has detected a voltage on the sensor's signal wire that is less than 0.5 volts for 5 seconds.
175-3 Engine Oil Temperature Sensor : Voltage Above Normal The ECM has detected a voltage on the sensor's signal wire that is greater than 4.8 volts for 5 seconds.
175-4 Engine Oil Temperature Sensor : Voltage Below Normal The ECM has detected a voltage on the sensor's signal wire that is less than 0.2 volts for 5 seconds.
542-3 Engine Oil Pressure Sensor - Before Oil Filter : Voltage Above Normal The ECM has detected a voltage on the sensor's signal wire that is greater than 4.8 volts for 5 seconds. Engine operation is not affected.
The value of the parameter is set to the last value from the sensor that is valid.
Monitoring for restriction of the oil filters is disabled.
The alarm output is activated.
The code is logged.
542-4 Engine Oil Pressure Sensor - Before Oil Filter : Voltage Below Normal The ECM has detected a voltage on the sensor's signal wire that is less than 0.2 volts for 5 seconds. The following analog sensors are used by these engines. Refer to Troubleshooting, "Component Location" for graphics that show the location of the sensor's on the in-line engines and on the vee engines.
Filtered engine oil pressure
Crankcase pressure
Inlet air temperature
Fuel temperature
Engine oil temperature
Unfiltered engine oil pressureBackground InformationThe ECM continuously creates a pull-up voltage on the signal wire for each sensor. The ECM uses this pull-up voltage in order to detect a problem in the signal circuit. When the ECM detects voltage that is above a threshold on the signal wire, the ECM activates a high voltage -3 diagnostic code. When the ECM detects voltage that is below a threshold on the signal wire, the ECM activates a low voltage -4 diagnostic code.Note: There may be a delay of 30 seconds or more in order for Caterpillar Electronic Technician (ET) to display an active diagnostic code. When you check for a diagnostic code, be sure to wait at least 30 seconds.The following components can cause these codes:
Electrical connector or wiring
Sensor
ECMThe most likely cause of a code is a problem with an electrical connector or wiring. The least likely cause of a code is the ECM.The ECM can be configured for one of these types of speed control:
0 to 5 V potentiometer
4 to 20 mAThe "DESIRED SPEED" potentiometer (if equipped) must be supplied with +5 VDC from the ECM. If the "DESIRED SPEED" potentiometer has a short circuit or the potentiometer's wiring has a short circuit, a 262-03 or 262-04 diagnostic code may be activated. There are no diagnostic codes for the circuit of the "DESIRED SPEED" potentiometer.
