Charge Air Cooler Temperature Sensor Circuit Intermittent/Erratic Bank 1
The P007E code indicates that the Powertrain Control Module (PCM) has detected an intermittent or erratic signal from the charge air cooler temperature sensor on Bank 1. This sensor monitors the temperature of the air exiting the intercooler, which is critical for proper air-fuel mixture and engine performance. An intermittent signal can be caused by a faulty sensor, damaged wiring, or poor electrical connections. This issue may lead to reduced engine power, poor fuel economy, and increased emissions.
01. Most Common Causes
- Faulty charge air cooler temperature sensor
- Damaged or corroded wiring/connectors
- Intermittent electrical connection
- PCM software issues (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine power or hesitation
- Poor fuel economy
- Rough idle or stalling
03. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm the code and check for other related codes.
Step 2: Visually inspect the sensor and wiring for damage, corrosion, or loose connections.
Step 3: Test the sensor resistance and compare to manufacturer specifications; replace if out of range.
Step 4: Check for intermittent issues by wiggling the wiring harness while monitoring the sensor signal with a scan tool.
