What Does P0824 Mean?
The gear lever Y position circuit is exhibiting intermittent behavior. The TCM is detecting erratic or momentarily lost signal from the Y-axis (fore-aft) position sensor. This intermittent condition often results in the TCM temporarily losing track of which gear the driver has selected.
Common Causes
30%
Intermittent wiring fault — broken conductor or chafed insulation in Y position circuit
30%
Loose or corroded connector at gear lever sensor causing poor contact
20%
Gear lever position sensor with internal intermittent failure
10%
Excessive shift lever bushing wear allowing abnormal movement
10%
TCM connector terminal tension loss
Diagnostic Steps
1
Monitor gear lever Y position voltage in live data while manipulating the connector and harness at the sensor to reproduce the intermittent.
2
Carefully inspect connector pins at the sensor and TCM for corrosion, backed-out pins, or widened female terminals.
3
Trace and flex the wiring harness from the sensor to the TCM, checking for voltage dropouts on the scan tool.
4
Inspect shift lever bushings for excessive wear that could cause physical misalignment with the sensor.
5
Replace the gear lever position sensor if wiring and connections test normal but the intermittent persists.
Estimated Repair Cost
$100 - $500

The gear lever Y position circuit is exhibiting intermittent behavior. The TCM is detecting erratic or momentarily lost signal from the Y-axis (fore-aft) position sensor. This intermittent condition often results in the TCM temporarily losing track of which gear the driver has selected.
The most common cause of P0824 (Gear Lever Y Position Circuit Intermittent) is: Intermittent wiring fault — broken conductor or chafed insulation in Y position circuit
Typical repair costs for P0824 range from $100 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The transmission may intermittently enter limp mode or momentarily lose gear position information. Driving is generally safe at moderate speeds, but the condition will likely worsen. Schedule repair soon.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0824 to identify the root cause.
