P2467: Exhaust Gas Temperature Sensor Circuit Range/Performance Bank 2 Sensor 3
The P2467 code indicates that the Engine Control Module (ECM) has detected a performance or range issue with the exhaust gas temperature (EGT) sensor located in Bank 2, Sensor 3 (downstream of the diesel particulate filter). This sensor monitors exhaust temperature for regeneration and emissions control. The ECM compares the sensor's signal to expected values; if the signal is out of range or changes too slowly, it sets this code. Common causes include a faulty sensor, wiring issues, or exhaust leaks.
1. Most Common Causes
- Faulty exhaust gas temperature sensor
- Wiring or connector damage (shorts, opens, corrosion)
- Exhaust leaks near the sensor
- ECM software or calibration issue
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced fuel economy
- Possible regeneration issues (DPF not regenerating properly)
- Possible limp mode or reduced engine power
3. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm the code and check for related codes (e.g., P2463, P2464).
Step 2: Visually inspect the EGT sensor and its wiring for damage, corrosion, or loose connections.
Step 3: Test the sensor's resistance and voltage output with a multimeter and compare to manufacturer specifications.
Step 4: Check for exhaust leaks upstream of the sensor using a smoke machine or visual inspection.
Step 5: If all else is fine, replace the EGT sensor and clear the code.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is generally safe for short distances, but prolonged driving may cause DPF clogging or reduced performance. Have it diagnosed promptly.
How much does it cost to fix?▼
The cost typically ranges from $150 to $400, including parts and labor. The sensor itself costs $50-$150, and labor adds $100-$250.
