P0792 Intermediate Shaft Speed Sensor Circuit Range/Performance

P0792 indicates range or performance trouble in the intermediate shaft speed sensor circuit. The speed signal exists but does not match expected gear behavior.

Code details

Generic OBD-II · P0

System: Transmission
Code type: Generic (SAE / ISO controlled)
Standard: SAE J2012 / ISO 15031-6

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not assume a slipping transmission until sensor data quality and reluctor condition are verified.

Symptoms of P0792

Harsh, delayed, or slipping shifts, or being stuck in one gear.
Check-engine light, sometimes with limp-home mode.
Flaring RPM or a shudder under load.

Common causes of P0792

Low or degraded transmission fluid.
A failing speed sensor, shift solenoid, or pressure-control circuit.
Wiring, connector, or internal hydraulic/mechanical faults.

Useful checks before replacing parts

Compare intermediate shaft speed with input and output speed during the shift or load condition that set the code.
Inspect sensor mounting, reluctor damage, internal harness, connector fit, and fluid contamination around the sensor.
Check for companion ratio or shift codes that can identify whether the signal is wrong or the transmission is slipping.
