P00E0 Code - Charge Air Cooler Coolant Temperature Sensor 'A' Circuit Low
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 P00E0 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 greater than a calibrated value or a short to ground is detected in the CACCTS circuit.
What are the Possible Causes of the DTC P00E0?
- 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 P00E0?
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 P00E0 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.

Frequently Asked Questions about P00E0 Code
1. What does the OBDII code P00E0 mean?
P00E0 indicates that the Charge Air Cooler Coolant Temperature Sensor 'A' circuit is reading a voltage lower than expected, which may affect engine performance.
2. What are the common symptoms of code P00E0?
Symptoms may include reduced engine performance, poor fuel efficiency, increased emissions, and the illumination of the check engine light.
3. What causes the P00E0 code to appear?
The code can be caused by a faulty temperature sensor, damaged or corroded wiring, loose electrical connections, or issues with the charge air cooler system.
4. How can I diagnose the P00E0 code?
Start by checking the sensor wiring and connectors for damage or corrosion, then test the Charge Air Cooler Coolant Temperature Sensor for proper functionality using a multimeter.
5. Can I continue driving with the P00E0 code?
While you may be able to drive with this code, prolonged operation can lead to reduced engine efficiency, higher emissions, and potential damage to the cooling system.
6. How do I fix the P00E0 code?
Repairs may include replacing the Charge Air Cooler Coolant Temperature Sensor, repairing damaged wiring, or cleaning corroded connections.
7. How much does it cost to repair the P00E0 code?
Costs vary but typically involve the price of a replacement sensor ($50–$150) and labor if professional service is required.
8. Can a dirty charge air cooler cause the P00E0 code?
Yes, if the cooler is clogged or inefficient, it can affect the temperature readings and trigger the code.
9. What tools do I need to fix the P00E0 code?
You may need a multimeter, basic hand tools, and possibly an OBDII scanner to diagnose and clear the code after repairs.
10. Will clearing the code fix the issue permanently?
Clearing the code without addressing the underlying problem will likely result in the code returning, as the system will detect the fault again.
