Mounting the Accelerator Position Sensor

6.2.2 Accelerator Pedal Position Sensor Duty Cycle

The Accelerator Pedal Position Sensor (APP Sensor) mounts directly to the pedal and should not be adjusted by the OEM. The OEM must insure that pedals supplied by the pedal manufacturer meet the following specification for sensor output duty cycle:

Accelerator Pedal Position Duty Cycle

Low idle 10% - 22%

High idle 75% - 90%

The pedal assembly should also conform to SAE J1843.

6.2.3 Accelerator Position Sensor for Remote PTO Applications

For applications also requiring variable engine speed control from outside of the cab, or from a linkage for special applications, a second accelerator pedal sensor input is available.

Figure 25 - 161-8906 Accelerator Position Sensor with Deutsch HD Connector

Caterpillar recommends the 161-8906 accelerator pedal position sensor for remote PTO applications. The sensor provides the same signal as the 176-1602, 176-1604, and the 176-1605 sensors, but requires battery voltage (12 or 24 volt systems) to operate.

6.2.4 161-8906 Accelerator Position Sensor Connector

The 161-8906 is supplied with a Deutsch HD plug connector (HD16-3-96S, Caterpillar P/N 8T-8731). The connecting harness will require a Deutsch HD receptacle connector (HD14-3-96P, Caterpillar P/N 8T-8732).

6.3 Mounting the Accelerator Position Sensor

The 161-8906 Accelerator Pedal Position Sensor can be attached to either an accelerator pedal assembly (contact the vehicle OEM for parts) or a Caterpillar 107-2281 PTO Accelerator Assembly. The PTO Accelerator Assembly does not include a handle. It may be used in applications where a mechanical linkage is required. The accelerator position sensor mounts directly to the PTO Accelerator Assembly and does not require additional sensor calibration.
