P007F medium Severity

P007F: Charge Air Cooler Temperature Sensor Bank1/Bank2 Correlation

Reduced engine performance and fuel efficiency; possible hesitation or altered turbo response

Overview

OBD-II P007F code indicates a correlation discrepancy between charge air cooler/intercooler temperature sensors on engine Bank 1 and Bank 2

Common Symptoms

  • Check Engine Light (MIL) illuminated
  • Reduced engine performance or power
  • Hesitation or rough acceleration
  • Increased fuel consumption
  • Hissing or abnormal intake noise

Most Common Causes

Faulty charge air cooler/intercooler temperature sensor high

Sensor reading divergence between banks triggers code

Wiring issues (open/short/corroded connectors) medium

Leads to inaccurate sensor readings

Actual intercooler issue (leak, blockage, uneven airflow) medium

Temperature difference may be real rather than electrical fault

PCM software or calibration error low

Consider after all sensor/wiring checks

Diagnostic Steps

  1. Retrieve stored codes and freeze frame data with an OBD-II scanner
    Expected: Confirmation of P007F and any associated codes
    Interpretation: Baseline data to understand operating conditions when fault occurred
  2. Visually inspect both charge air cooler temperature sensors, connectors, and wiring harness
    Expected: No damage, corrosion, disconnections
    Interpretation: Damage suggests wiring/sensor cause
  3. Compare live sensor data from both Bank 1 and Bank 2 while engine running
    Expected: Similar correlated temperature values
    Interpretation: Large discrepancy confirms true mismatch
  4. Test wiring continuity and reference voltage for each sensor circuit
    Expected: Proper 5V reference and good continuity
    Interpretation: Failures point to wiring or PCM issues
  5. Test individual sensor resistance/voltage per OEM spec
    Expected: Sensor values within specifications
    Interpretation: Out-of-spec indicates defective sensor

Repair Solutions

Replace defective charge air cooler temperature sensor(s) medium
Estimated Cost: $100 - $400

Cost varies by vehicle and parts/labor rates

Repair or replace damaged wiring/connectors medium
Estimated Cost: $50 - $300

Depends on extent of wiring damage

Inspect and repair intercooler or air intake system (leaks/obstructions) hard
Estimated Cost: $200 - $800

Major intercooler repairs can be costly

Update or reprogram PCM medium
Estimated Cost: $100 - $300

Consider only after ruling out sensor/electrical causes

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Ambient temperature sensor fault (incorrectly assumed when code pertains to intercooler sensors)

Frequently Asked Questions

What does the P007F code mean?

The P007F code stands for Charge Air Cooler Temperature Sensor Bank1/Bank2 Correlation. This generally indicates an issue with the Air Intake system.

Can P007F cause engine damage?

You should treat P007F as a medium issue. Reduced engine performance and fuel efficiency; possible hesitation or altered turbo response

Symptoms associated with DTC P007F

Drivers often report: Check Engine Light (MIL) illuminated, Reduced engine performance or power, Hesitation or rough acceleration when this code is present.

Why is my car throwing a P007F code?

It can be caused by several factors, most notably: Faulty charge air cooler/intercooler temperature sensor, Wiring issues (open/short/corroded connectors), Actual intercooler issue (leak, blockage, uneven airflow).

Repair cost breakdown for P007F

The cost varies significantly based on the root cause. For example, replacing a Repair or replace damaged wiring/connectors typically costs between $50 and $300, while fixing a Inspect and repair intercooler or air intake system (leaks/obstructions) can range from $200 to $800.

What cars are affected by the P007F code?

P007F is not specific to any one brand. It can appear on Ford, Dodge, Toyota, Honda, Jeep, and other vehicles.
