What Does P082B Mean?
The gear lever X position circuit is reading low voltage. The TCM has detected that the X-axis position sensor output is below the minimum expected threshold. This typically indicates a short to ground in the sensor circuit, a failed sensor with low output, or a wiring fault pulling the signal low.
Common Causes
30%
Gear lever X position sensor failure producing low output
30%
Short to ground in the X position sensor signal wire
20%
Corroded connector causing signal attenuation
10%
Loss of 5V reference supply to the sensor
10%
TCM internal input circuit pulling signal low
Diagnostic Steps
1
Measure voltage at the gear lever X position sensor signal pin with the connector attached — compare to minimum specification.
2
Check the 5V reference supply voltage at the sensor connector. If missing, trace the reference wire back to the TCM.
3
Disconnect the sensor and measure voltage at the TCM side of the harness to isolate whether the fault is in the sensor or wiring.
4
Inspect the wiring for shorts to ground, particularly where the harness runs near metal brackets or through grommets.
5
Replace the gear lever position sensor if the wiring and reference supply test normal.
Estimated Repair Cost

The most common cause of P082B (Gear Lever X Position Circuit Low) is: Gear lever X position sensor failure producing low output
Typical repair costs for P082B range from $150 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The TCM may not correctly identify the gear lever position, causing incorrect shift commands or limp mode. Drive with caution and avoid high-speed driving until the issue is resolved.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P082B to identify the root cause.
