P00CE Code - Intake Air Temperature Measurement System Multiple Sensor Correlation

Quick Answer

The Powertrain Control Module (PCM) monitors the intake air system for concerns at ignition start. Common causes include Faulty Intake Air Temperature (IAT), Charge Air Cooler Temperature (CACT) or Intake Air Temperature 2 (IAT2) Sensor, Contaminated or blocked sensors, Slow responding sensors. 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 P00CE Description

The Powertrain Control Module (PCM) monitors the intake air system for concerns at ignition start. The test fails when the Intake Air Temperature (IAT), Charge Air Cooler Temperature (CACT) and the Intake Air Temperature 2 (IAT2) Parameter Identifications (PIDs) are each more than 16.67°C (30°F) different from each other at start-up. The Diagnostic Trouble Code (DTC) will be set when the PCM detects that each sensor is out of the calibrated range at engine start-up after a soak period of at least 6 hours when a block heater is not used.

Slow responding sensors

How to Fix the DTC P00CE?

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 P00CE 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.
