Gear Lever Y Position Circuit Intermittent
The P0824 code indicates an intermittent fault in the gear lever Y position circuit, which is part of the transmission range sensor system. This sensor tells the powertrain control module (PCM) the position of the gear selector. An intermittent signal can cause erratic shifting, incorrect gear display, or prevent starting. The issue may stem from a faulty sensor, damaged wiring, or poor electrical connections.
01. Most Common Causes
- Faulty transmission range sensor (gear lever position sensor)
- Damaged or corroded wiring/connectors in the Y position circuit
- Intermittent short or open circuit due to vibration or moisture
- Faulty PCM (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Incorrect gear position display on dashboard
- Engine may not start or start in wrong gear
- Erratic or harsh shifting
03. Step-by-Step Diagnosis
Step 1: Scan for additional codes and record freeze frame data.
Step 2: Visually inspect the gear lever position sensor and wiring for damage, corrosion, or loose connections.
Step 3: Test the sensor's resistance and voltage according to manufacturer specifications.
Step 4: Check for intermittent faults by wiggling wiring harness while monitoring sensor signal with a multimeter or scan tool.
Step 5: If sensor and wiring are good, test PCM input/output for the circuit.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended. The intermittent circuit can cause sudden loss of gear position signal, leading to unexpected shifting or inability to start, which may be dangerous.
How much does it cost to fix?▼
Typically $50-$150 for diagnosis and repair, but if the sensor needs replacement, parts and labor can range from $100-$300.
