Exhaust Gas Temperature Out of Range Bank 2 Sensor 4
P247F relates to exhaust gas temperature out of range bank 2 sensor 4. Check the fault conditions and vehicle-specific procedure before replacing parts.
What you may notice
Symptoms
- 01Warning light may illuminate
- 02Related system function may be impaired
- 03Vehicle-specific symptoms vary
Where to look first
Common causes
- 01Exhaust or emissions plumbing leak, restriction, valve fault, sensor fault, or damaged wiring
- 02Related wiring, connector, power or ground fault
- 03Vehicle-specific mechanical or control issue
A sensible sequence
Best diagnostic order
- 01Record stored and pending codes and freeze-frame data
- 02Inspect the relevant exhaust or emissions plumbing and electrical connections, then compare commanded operation with sensor feedback during the enable conditions.
- 03Confirm measured values against the vehicle service information
- 04Retest under the conditions that set the code
Step by step
What to check and repair
- 01Inspect the relevant exhaust or emissions plumbing and electrical connections, then compare commanded operation with sensor feedback during the enable conditions.
- 02Repair the verified cause and confirm the code does not return
Read the signals
Live-data clues
Emissions system command and feedback
- Typical behavior
- Consistent with the vehicle specifications and operating conditions
- Possible clue
- A dropout or implausible value can localize the fault
| Parameter | Typical behavior | What it can suggest |
|---|---|---|
| Emissions system command and feedback | Consistent with the vehicle specifications and operating conditions | A dropout or implausible value can localize the fault |
What P247F means
Exhaust Gas Temperature Out of Range Bank 2 Sensor 4. This diagnostic trouble code identifies a detected condition; it does not by itself identify the failed part.
Diagnostic direction
Inspect the relevant exhaust or emissions plumbing and electrical connections, then compare commanded operation with sensor feedback during the enable conditions.
Before clearing the code
Record stored and pending codes and freeze-frame data. Confirm specifications and tests for the exact vehicle. Repair the verified cause, then repeat the appropriate monitor or drive cycle.
