P007E: Charge Air Cooler Temperature Sensor Circuit Intermittent/Erratic Bank 1

The charge air cooler temperature sensor (an NTC thermistor) measures the temperature of the compressed charge air at the charge air cooler, depending on the manufacturer upstream or downstream of it, and is often combined with the boost pressure sensor. The engine control module uses it for the air mass calculation, boost control, component protection and to monitor cooler efficiency. P007E is set when the signal jumps beyond a plausible rate of change, which typically points to a loose contact.

Low severity. Can I keep driving?Yes, you can normally keep driving and take it to a repair shop when convenient.

Bank 1 is the side of the engine with cylinder 1. Inline engines only have this bank.

Symptoms

Check engine light on
Reduced power possible, especially on diesels
Often no noticeable symptoms

Most likely causes

Loose contact or corroded connector
Wire chafed at the engine
Sensor faulty

What to check, in order

Start with the simplest. You can tick off each step.

With the engine cold, compare the reading with the outside temperature
Gently move the wiring with the engine running and watch whether the reading changes.
Check the connector
Measure the sensor's resistance against the manufacturer's specification
Check power and ground before replacing it

Good to know

Repair difficulty: easy
It can trigger limp mode.
It affects emissions.

What each character of P007E means

P: Powertrain: engine and transmission
0: Generic code: same on every make
0: Subsystem depends on the code range
7E: Specific fault in that system
