91-3
Accelerator Pedal Position #1 : Voltage Above Normal     91-3
Throttle Position Sensor : Voltage Above Normal     The Electronic Control Module (ECM) detects a voltage that is above normal in the circuit for the throttle position sensor.    
91-4
Accelerator Pedal Position #1 : Voltage Below Normal     91-4
Throttle Position Sensor : Voltage Below Normal     The ECM detects a voltage that is below normal in the circuit for the throttle position sensor.    
91-8
Accelerator Pedal Position #1 : Abnormal Frequency, Pulse Width, or Period     91-8
Throttle Position Sensor : Abnormal Frequency, Pulse Width, or Period     The ECM detects an incorrect frequency or an incorrect duty cycle in the circuit for the throttle signal. The engine speed is limited to low idle.    System OperationUse this procedure to troubleshoot any suspect problems with the sensor for the left turbocharger turbine inlet temperature or the right turbocharger turbine inlet temperature.The Pulse Width Modulated Sensor (PWM) provides a signal to the ECM. The PWM signal is used to represent certain engine operating conditions. The sensors receive 8.0 0.4 VDC from a regulated power supply.The ECM performs an automatic calibration of these sensors whenever the ECM is powered and the engine has been off for at least 5 seconds.The ECM provides short circuit protection for the internal power supply. A short circuit to the battery will not damage the internal power supply.The following components can cause problems with the power supply:
Electrical connector or wiring
Sensor
ECMThe most likely cause of a problem is a problem with an electrical connector or wiring. The least likely cause is a problem with the ECM.

Troubleshooting Test Steps    Values    Results    
1. Check for Diagnostic Codes
A. Turn the keyswitch to the ON position.
B. Establish communication between Caterpillar Electronic Technician (ET) and the ECM. Refer to Troubleshooting, "Electronic Service Tools" if necessary.
C. Look for diagnostic codes.
   
Diagnostic Codes
   
Results: A -3 code is active or logged.
Proceed to Test Step 2.
Results: A -4code is active or logged.
Proceed to Test Step 3.
Results: A -8 code is active or logged.
Proceed to Test Step 5.
   
2. Create a Short at the Sensor Connector
A. Turn the keyswitch to the OFF position.
B. Use a jumper wire in order to create a short between terminal 3 (signal) and terminal 2 (sensor return) at the sensor connector.
C. Turn the keyswitch to the ON position.
D. Monitor the diagnostic codes on Cat ET. Check for an active -4 diagnostic code for the suspect sensor.
   
Short Created
   
Results: A -4 diagnostic code became active after creating the short at the sensor connector.
The wiring is OK.
Repair: Replace the sensor.
Verify that then problem is resolved.
Results: A -4 diagnostic code does not become active for the suspect sensor.
Proceed to Test Step 4.
   
3. Create an Open at the Suspect Sensor Connector
A. Turn the keyswitch to the OFF position.
B. Disconnect the sensor connector of the suspect sensor with the active -4 diagnostic code.
C. Turn the keyswitch to the ON position.
D. Monitor the diagnostic codes on Cat ET. Check for an active -3 diagnostic code for the suspect sensor.
   
Create an Open
   
Results: A -3 diagnostic code became active after disconnecting the sensor.
The wiring is OK.
Repair: Replace the sensor.
Verify that then problem is resolved.
Results: A -3 diagnostic code did not become active after disconnecting the sensor.
Proceed to Test Step 4.
   
4. Check the 8 VDC Supply Voltage at the Sensor Connector
A. Turn the keyswitch to the ON position.
B. Measure the voltage between pin 1 and pin 2 at the suspect sensor.
   
Test passed
   
Results: The supply voltage is approximately 8.0 0.2 VDC.
Connect the sensor and then proceed to Test Step 8.
Results: The supply voltage is not approximately 8.0 0.2 VDC.
There is a short in the harness to the battery.
Repair: Repair the wiring or replace the harness.
Verify that the problem is resolved.
Return to Service.
   
5. Check the PWM Circuit for an Open
A. Turn the keyswitch to the OFF position.
B. Disconnect the sensor connector of the suspect sensor with the active -8 diagnostic code.
C. Disconnect the J2 connector at the ECM.
D. Measure the resistance between the suspect sensor PWM signal wire (pin 3 on the sensor connector) and the appropriate PWM signal wire on the ECM connector. Refer to the appropriate schematic.
   
Open Circuit
   
Results: Less than 10 ohms of resistance between the sensor connector and the ECM connector.
Proceed to Test Step 6.
Results: More than 10 ohms of resistance between the sensor connector and the ECM connector.
There is an open
