Gear Lever X Position Circuit Low
The P082B code indicates that the Powertrain Control Module (PCM) has detected a low voltage condition in the gear lever X position sensor circuit. This sensor is part of the transmission range sensor assembly, which tells the PCM the selected gear position. A low circuit voltage typically means a short to ground, a faulty sensor, or a wiring issue. This can cause incorrect gear selection, transmission shifting problems, and may prevent the vehicle from starting or moving.
01. Most Common Causes
- Faulty gear lever position sensor
- Short to ground in the sensor circuit wiring
- Damaged connector or corroded terminals
- Failed PCM (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Transmission stuck in one gear or fails to shift
- Incorrect gear indication on dashboard
- Vehicle may not start or move
03. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm the code and check for other related codes.
Step 2: Inspect the gear lever position sensor connector and wiring for damage, corrosion, or shorts to ground.
Step 3: Test the sensor's voltage and resistance per manufacturer specifications; replace if out of range.
Step 4: If sensor and wiring are okay, check for PCM issues; reprogram or replace if necessary.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
No, it is not safe. The transmission may not shift properly or could get stuck in gear, leading to loss of vehicle control or transmission damage.
How much does it cost to fix?▼
Typically $50-$150 for diagnosis and sensor replacement, but costs can vary depending on labor rates and parts.
