Causes

Open or high-resistance in solenoid wiring (broken conductor, corrosion, poor pin contact)
Faulty gear-shift lock solenoid (coil partially open or internally damaged)
Faulty transmission control module (TCM) or body control module (BCM) driver transistor
Blown or high-resistance fuse or fusible link in the solenoid supply circuit
Poor or corroded ground(s) for the solenoid circuit
Aftermarket modifications or recent repairs that disturbed the harness

Symptoms

Transmission shift-lock fails to engage or release (may prevent shifting out of Park)
Intermittent or permanent inability to shift gears or abnormal shift behavior
MIL (check engine lamp) or transmission warning lamp illuminated
Stored or intermittent P092D (plus possibly other transmission/shift lock related codes)
No audible click from solenoid when attempting to operate shift lock

What to check

Read and record freeze-frame and all stored codes with a capable scan tool (check for related codes)
Visual inspection of solenoid B connector, wiring harness and nearby chassis for damage, corrosion, or pinched sections
Check fuses and fusible links related to transmission/shift lock circuit
Back-probe solenoid connector while attempting activation to measure supply and driver voltages
Measure solenoid coil resistance with the connector disconnected
Perform an active test / command of the shift lock solenoid using a factory-level scan tool (if available)

Signal parameters

Expected supply voltage: battery voltage ~11–14 V with ignition ON (verify on vehicle)
Driver output: near 0 V (ground) when activated; open/high when inactive for circuits switched to ground — may be PWM depending on vehicle
Typical solenoid coil resistance (vehicle-specific) commonly in the low ohms to tens of ohms range (example 5–50 Ω); consult Land Rover factory data for exact spec
No-DTC idle: circuit continuity from module pin to solenoid with low resistance and good ground

Diagnostic algorithm

Connect an advanced scan tool and read all transmission and body module codes; note pending codes and freeze frame data
Visually inspect the gear shift lock solenoid B connector and harness for corrosion, bent pins, melting, or water damage; repair or replace damaged connector as needed
Check relevant fuses and battery supply to solenoid circuit; replace any blown or suspect fuses and re-test
With ignition ON, back-probe the solenoid connector: verify battery feed at the supply terminal and monitor the driver terminal while commanding solenoid ON from the scan tool. Record voltages.
Measure coil resistance at the disconnected solenoid connector. Compare to factory spec. If open or out of range, replace the solenoid.
If coil resistance is correct and supply is present but driver does not switch: check continuity from module driver pin to solenoid connector pin and inspect/repair any wiring faults.
If wiring and solenoid check OK, test the control module output. Check for correct switching to ground (or expected PWM) using an oscilloscope or DVOM; if the module driver is stuck high or not switching, consider module diagnostics/repair.
If intermittent fault reproduces when flexing the harness, repair or replace the harness section and re-check.
After repairs or parts replacement, clear codes and perform a functional test: command the solenoid repeatedly, road test as appropriate, and confirm no reoccurrence of P092D.
If control module replacement is required, verify root cause and ensure wiring/grounds are good before replacing the module to avoid repeat failure.

Likely causes

Connector corrosion at solenoid B (water ingress, bent pins)
Intermittent open in harness due to chafing or pinched cable under chassis/console
Solenoid B has increased coil resistance or intermittent internal open
Control module output stage (driver) failed high or not switching to ground
Fuse for solenoid supply is degraded or poor ground connection

Fault status

⚠️ Status

P092D — Gear shift lock solenoid B circuit high. Electrical fault detected in the solenoid B circuit or its driver; inspect wiring, connectors, supply/fuses, grounds, and solenoid unit.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 1 - 3 hours
