P00CE Mercury 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 Mercury 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.

Frequently Asked Questions about P00CE Mercury Code

1. What are the common symptoms of OBDII code P00CE (Intake Air Temperature Measurement System Multiple Sensor Correlation) in a Mercury vehicle?

- Common symptoms may include poor engine performance, reduced fuel efficiency, rough idling, and potential stalling.

2. What could cause the OBDII code P00CE to trigger in a Mercury?

- The code may be triggered by issues such as faulty intake air temperature sensors, wiring problems, or a malfunction in the engine control module (ECM).

3. How can I diagnose the cause of OBDII code P00CE in my Mercury?

- Diagnosis typically involves checking the intake air temperature sensor readings, inspecting the sensor wiring for damage, and performing a thorough scan of the ECM for potential faults.

4. Can a dirty air filter cause the OBDII code P00CE to appear in a Mercury?

- Yes, a dirty air filter can disrupt the intake air temperature readings and potentially lead to the triggering of code P00CE.

5. Is it safe to continue driving my Mercury with the OBDII code P00CE present?

- It is not recommended to drive the vehicle for an extended period with the code active, as it can lead to further engine complications and potential damage.

6. What are some repair tips for resolving OBDII code P00CE in a Mercury?

- Repair tips may include cleaning or replacing the intake air temperature sensors, repairing any damaged wiring, and resetting the ECM to clear the code.

7. Can resetting the ECM clear the OBDII code P00CE in a Mercury?

- Resetting the ECM may temporarily clear the code, but if the underlying issue causing the code is not addressed, it is likely to reappear.

8. How much does it typically cost to repair OBDII code P00CE in a Mercury?

- The cost of repair can vary depending on the exact cause of the issue, but it may range from a simple sensor replacement to more extensive wiring repairs.

9. Are there any recalls or technical service bulletins related to OBDII code P00CE in Mercury vehicles?

- It is advisable to check with a Mercury dealership or online resources for any relevant recalls or technical service bulletins related to this specific OBDII code.

10. Can I attempt to fix OBDII code P00CE in my Mercury myself, or should I seek professional help?

- While some simple repairs like sensor replacement may be done by DIY enthusiasts, it is recommended to consult with a professional mechanic for a proper diagnosis and repair of the issue.
