What vehicles are most commonly affected by P007C?

DTC P007C is commonly reported in vehicles like the 2015-2018 Ford Escape, 2016-2019 Honda Civic, and various models from Chevrolet and Nissan, particularly those with turbocharged engines.

How can I prevent P007C from happening again?

Regular maintenance, including checking and cleaning electrical connections and sensors, can help prevent P007C. Additionally, addressing any performance issues promptly can prevent further damage to the intake air temperature sensor.

What is P007C?

DTC P007C indicates a problem with the intake air temperature (IAT) sensor circuit, specifically relating to its range or performance. This code typically arises when the vehicle's engine control unit (ECU) detects a discrepancy between the actual temperature of the incoming air and the expected temperature value. The IAT sensor plays a critical role in optimizing engine performance by measuring the temperature of the air entering the engine. This information helps the ECU adjust fuel delivery and ignition timing for optimal combustion. If P007C is triggered, it can lead to poor fuel efficiency, reduced engine performance, and increased emissions. In practical terms, car owners may notice their vehicle struggling during acceleration or experiencing rough idling. Common vehicle makes/models that report this issue include the 2015-2018 Ford Escape and the 2016-2019 Honda Civic. Ignoring this code may lead to further engine complications, so timely diagnostics and repairs are crucial.

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

Symptoms

Common symptoms when P007C is present:

  • Check engine light remains illuminated, indicating an issue that needs attention.
  • Engine performance may suffer; drivers often report sluggish acceleration or reduced power during highway merging.
  • Decreased fuel economy; owners might notice a drop in miles per gallon due to improper air-fuel mixture adjustments.
  • Unusual engine behavior, such as stalling or rough idling, especially after starting the engine.
  • Increased engine emissions, which may cause the vehicle to fail an emissions test.

Possible Causes

Most common causes of P007C (ordered by frequency):

  1. Faulty intake air temperature sensor - Most common cause, often occurring in approximately 40-50% of cases. This sensor can wear out over time due to heat exposure.
  2. Wiring issues or corroded connectors in the IAT circuit - These problems can account for about 25% of cases. Inspecting wiring for damage or corrosion is essential.
  3. Malfunctioning engine control unit (ECU) - While less common, a faulty ECU can cause incorrect readings and is a potential cause that demands immediate attention.
  4. Vacuum leaks - These can lead to incorrect air-fuel mixture readings, affecting the IAT sensor's operation and constituting about 15% of cases.
  5. Issues with the mass airflow sensor (MAF) - A malfunctioning MAF can also affect the IAT readings and should be examined during diagnostics.
