P00E1 Code - Charge Air Cooler Coolant Temperature Sensor 'A' Circuit High
Quick Answer
The Charge Air Cooler (CAC) Coolant Temperature Sensor (CACCTS) is a thermistor device in which resistance changes with the temperature. Common causes include Faulty Charge Air Cooler (CAC) Coolant Temperature Sensor (CACCTS), Charge Air Cooler Coolant Temperature Sensor harness is open or shorted, Charge Air Cooler Coolant Temperature Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P00E1 Description
Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so varying the resistance of the passive sensor causes a variation in total current flow. The voltage that is dropped across a fixed resistor (pull-up resistor) in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.
The Charge Air Cooler Coolant Temperature Sensor is installed on the side of the CAC radiator and measures the CAC system coolant temperature. The PCM uses the CAC coolant temperature sensor to determine the desired operating condition of the CAC coolant pump.
This Diagnostic Trouble Code (DTC) will be set when the Charge Air Cooler Coolant Temperature is less than a calibrated value or a short to voltage is detected in the CACCTS circuit.
What are the Possible Causes of the DTC P00E1?
- Faulty Charge Air Cooler (CAC) Coolant Temperature Sensor (CACCTS)
- Charge Air Cooler Coolant Temperature Sensor harness is open or shorted
- Charge Air Cooler Coolant Temperature Sensor circuit poor electrical connection
How to Fix the DTC P00E1?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P00E1 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
