P00E0 medium Severity

P00E0: Charge Air Cooler Coolant Temperature Sensor 'A' Circuit Low

May lead to improper temperature readings affecting engine performance and efficiency

Overview

P00E0 indicates a low circuit voltage or fault condition detected in the charge air cooler coolant temperature sensor A circuit, potentially due to sensor, wiring, or related control issues

Common Symptoms

  • Check Engine Light illuminated
  • Abnormal engine temperature readings
  • Reduced engine performance

Most Common Causes

Faulty charge air cooler coolant temperature sensor medium

Sensor may provide low voltage or incorrect readings triggering the code

Damaged wiring harness or connectors in sensor circuit medium

Open, shorted, or corroded wiring/connectors can cause low circuit voltage

Poor reference voltage or grounding issue low

Voltage supply issues may mimic a low circuit condition

Engine control module (ECM) fault low

ECM rare cause but possible if internal circuitry misinterprets sensor signal

Diagnostic Steps

  1. Retrieve and confirm the P00E0 code using an OBD2 scanner
    Expected: Code P00E0 present with freeze frame data
    Interpretation: Verifies the fault is active or stored
  2. Perform visual inspection of charge air cooler coolant temperature sensor wiring and connectors
    Expected: No broken, corroded, or disconnected wiring
    Interpretation: Poor wiring/connectors often cause circuit low conditions
  3. Test sensor signal and reference voltage with multimeter against manufacturer specs
    Expected: Proper voltage and resistance readings
    Interpretation: Out-of-spec readings indicate sensor or circuit issue
  4. If wiring and sensor tests pass, check ECM inputs and grounding
    Expected: Proper signal continuity to ECM
    Interpretation: Fault here suggests control module or harness issue

Repair Solutions

Replace charge air cooler coolant temperature sensor medium
Estimated Cost: $80 - $250

Sensor replacement often resolves low circuit conditions
