Cylinder 10 Glow Plug Incorrect
The P06CE code indicates that the Engine Control Module (ECM) has detected an incorrect glow plug in cylinder 10. This typically means the glow plug resistance or current draw is out of expected range, often due to a faulty glow plug, wiring issues, or a failed glow plug control module. This condition can cause hard starting, misfires, and increased emissions in diesel engines.
1. Most Common Causes
- Glow plug in cylinder 10 is damaged or has resistance out of specification
- Wiring or harness for glow plug circuit 10 is shorted, open, or has high resistance
- Electrical connector for cylinder 10 is corroded, bent, or has poor connection
- Glow plug control module is faulty
- Glow plug system relay or fuse has intermittent failure
- Engine control module (ECM) is damaged (uncommon)
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Hard starting, especially in cold weather
- Rough idle or misfire on cylinder 10
- Excessive white smoke on startup
3. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect glow plug wiring and connector at cylinder 10 for damage or corrosion.
Step 3: Measure glow plug resistance with a multimeter; compare to specifications (typically 0.5-2 ohms).
Step 4: Test glow plug control module output to cylinder 10 using a test light or multimeter.
Step 5: Replace glow plug if resistance is out of spec; repair wiring or replace module as needed.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances, especially in cold weather, as it can cause hard starting, increased emissions, and potential engine damage from unburned fuel.
How much does it cost to fix?▼
Typically $50-$150 for a single glow plug replacement, including parts and labor. Costs may be higher if the glow plug module or wiring needs repair.
