Short to ground on sensor B signal wire
Poor or corroded connector/terminal at gear lever position sensor
Faulty gear lever position sensor (internal short or failed potentiometer/switch)
Damaged wiring harness (chafing, pinched, broken conductor)
Incorrect or missing reference/ground supply from ECU
Intermittent connection or water intrusion at connector

Read freeze frame and pending codes; confirm P2E06 is current or stored
Visually inspect gear lever area, sensor connector and wiring for damage, corrosion, or water ingress
Check for related codes (other gear lever sensor codes or PRNDL codes)
With ignition ON (engine off), backprobe sensor connector and measure reference, signal and ground voltages
Perform continuity check of signal wire to ECM connector and check for short to ground
Wiggle wiring and connector while monitoring signal to check for intermittent faults

Reference supply: approximately 5.0 V (ignition ON) (varies by vehicle)
Signal output: typically 0.5–4.5 V depending on lever position; a low fault often shows
Ground: near 0 V at sensor ground pin
Expected resistance: sensor pot/switch values vary by design — often in the kiloohm range; consult vehicle-specific specs
If reference present and signal

Verify vehicle safety: parking brake set, ignition OFF when connecting or disconnecting connectors where appropriate.
Read and record freeze frame, readiness, and all related codes with a scan tool.
Visually inspect the gear lever sensor, mounting, connector and harness for damage, corrosion, pulled pins or water entry.
With ignition ON (engine not running), backprobe connector: confirm reference voltage (~5 V) and ground presence. If reference is missing, trace power supply/fuse/ECM output.
Measure signal pin voltage while moving gear lever through positions. Normal operation should show a changing voltage. If signal remains low (
If signal is low, disconnect sensor and measure resistance between signal and ground pins for short. Also check continuity between signal pin and the ECM pin. If short to ground persists with sensor disconnected, repair wiring to ECM.
Repair or replace damaged wiring, repair corroded connector terminals, or replace faulty sensor as indicated by tests.
After repair, clear codes, perform relearn procedures if required by manufacturer, and verify proper operation with scan tool and road test.
If wiring and sensor check good but fault returns, test or replace the control module only after confirming wiring and sensor integrity.
