P007B: Charge-air-cooler temperature sensor, bank 1 — range/performance — what it means, the affected system and what to check before replacing parts.
Meaning, symptoms, causes and checks
The controller reports a plausibility or range/performance fault in the charge-air-cooler temperature sensor on bank 1. In one documented Ford monitor, sensor temperature is compared with other temperature readings under specified operating conditions; those enable conditions and thresholds do not apply universally. This is not proof that the sensor itself must be replaced.
Affected system: Charge-air temperature monitoring
Symptoms
- Warning light may illuminate
- Related system function may be impaired
- Vehicle-specific symptoms vary
Possible causes
- Implausible sensor or switch signal, poor ground, connector corrosion, or wiring damage
- Related wiring, connector, power or ground fault
- Vehicle-specific mechanical or control issue
What to check
- Record stored and pending codes and freeze-frame data
- Compare the named sensor or switch signal with actual operating conditions; inspect the connector, reference supply, ground and harness.
- Confirm measured values against the vehicle service information
- Retest under the conditions that set the code
- Compare the named sensor or switch signal with actual operating conditions; inspect the connector, reference supply, ground and harness.
- Repair the verified cause and confirm the code does not return
Also written as: P007B-00, P007B00, PO07B (some scan tools add the fault-type byte, e.g. -00).
