P0822 Gear Lever Y Position Circuit

P0822 points to a gear lever Y position circuit fault. The fore-aft shifter position signal is not valid enough for the module to trust.

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 diagnose a shift internal fault before confirming that the shifter Y signal is accurate.

Symptoms of P0822

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 P0822

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

Monitor gear lever Y position during every shifter movement and compare the data to actual lever travel and detents.
Check sensor reference voltage, ground, signal continuity, connector condition, linkage movement, and contamination inside the shifter.
Review companion X position, range sensor, or manual-mode codes to identify whether the shifter assembly has a shared fault.
