Common Questions

What does P00E3 mean and how does it affect my car?

The P00E3 code indicates a problem with the air intake temperature sensor circuit, which can lead to reduced engine performance, poor fuel economy, and potential long-term engine damage if not addressed.

What are the most common causes of P00E3 and how much does it cost to fix?

Common causes of the P00E3 code include a faulty mass airflow sensor, damaged wiring, and vacuum leaks. Repair costs can range from $100 for wiring repairs to $400 for sensor replacements.

Can I drive my car with P00E3 or should I stop immediately?

While you may still be able to drive your vehicle, it is advisable to address the P00E3 code promptly to avoid worsening engine performance and potential damage.

How can I diagnose P00E3 myself using GeekOBD APP?

To diagnose P00E3 with the GeekOBD APP, connect the device to your vehicle, scan for codes, and review the freeze frame data to understand the fault context. Testing the MAF and IAT sensors can also be done with this app.

What vehicles are most commonly affected by P00E3?

The P00E3 code is frequently encountered in 2015-2018 Ford F-150 models, though it can affect various makes and models, including some Honda and Chevrolet vehicles.

How can I prevent P00E3 from happening again?

Regular maintenance of your vehicle, including checking air filters and inspecting wiring, can help prevent the P00E3 code from reappearing. Additionally, using high-quality air filters can improve airflow and reduce strain on the MAF sensor.

What is P00E3?

The P00E3 diagnostic trouble code indicates an issue with the mass airflow sensor (MAF) or the air intake system in your vehicle. This code is particularly common in 2015-2018 Ford F-150 models, although it can appear in other vehicles as well. Essentially, this code suggests that the Engine Control Module (ECM) has detected a problem with the air intake temperature sensor circuit. When the ECM identifies that the air temperature readings are not within the expected range, it triggers the check engine light and may affect engine performance. Ignoring this code can lead to reduced fuel efficiency, poor acceleration, and even long-term engine damage if the issue is not resolved. A malfunctioning MAF sensor can cause the engine to run too rich or too lean, leading to other problems such as increased emissions and rough idling. Therefore, it's crucial to address any P00E3 code quickly to ensure the longevity and performance of your vehicle.

System: P - Powertrain (Engine, Transmission, Emissions)

Symptoms

Common symptoms when P00E3 is present:

The check engine light illuminates, indicating a problem with the air intake system.
You may notice a significant loss of power during acceleration, often feeling sluggish and unresponsive.
Fuel economy may decrease, with some drivers reporting reductions of 10-15% due to improper air-fuel mixture.
Engine stalling or rough idling can occur, particularly when coming to a stop or at low speeds.
In extreme cases, the vehicle may enter 'limp mode', restricting speed and power to protect the engine.

Possible Causes

Most common causes of P00E3 (ordered by frequency):

{'cause': 'Faulty mass airflow sensor (MAF) - 50% likelihood', 'details': "The MAF sensor is crucial for measuring the amount of air entering the engine. If it's malfunctioning, the ECM may not receive accurate data, leading to the P00E3 code."}
{'cause': 'Wiring issues - 25% likelihood', 'details': 'Damaged wiring or corroded connectors in the air intake temperature sensor circuit can lead to erroneous readings and trigger the P00E3 code.'}
{'cause': 'Vacuum leaks - 15% likelihood', 'details': 'A vacuum leak in the intake system can disrupt the air-fuel mixture, causing the engine to run poorly and potentially triggering the P00E3 code.'}
{'cause': 'Faulty intake air temperature sensor - 5% likelihood', 'details': 'Although less common, a failing intake air temperature sensor can also be responsible for triggering the P00E3 code.'}
{'cause': 'ECM malfunction - 5% likelihood', 'details': 'Rarely, the engine control module itself may have issues that could lead to the P00E3 code appearing.'}

P00E3 Repair Costs

Cost Breakdown by Repair Type

Replace Mass Airflow Sensor

Replacing the faulty MAF sensor can resolve the P00E3 code and restore proper engine performance.

Total: $200 - $400
Success rate: 90%

Repair Wiring Issues
