P00AB Fault Code

Intake Air Temperature Sensor 1 Circuit Range/Performance Bank 2

• What does that mean?
• Symptoms
• Causes
• Solutions

• The P00AB code indicates an issue with the Intake Air Temperature (IAT) Sensor 1 circuit specifically for Bank 2.
• This sensor plays a crucial role in measuring the temperature of the air entering the engine, which is essential for optimizing fuel injection and ignition timing.
• When the temperature readings are incorrect or out of range, it can affect overall engine performance, fuel efficiency, and emissions.

What are the symptoms of the P00AB code?

• Symptoms of a P00AB code may include:
  • Check Engine Light illuminated on the dashboard
  • Poor engine performance or hesitation during acceleration
  • Decreased fuel efficiency
  • Rough idling or stalling
  • Engine overheating in some cases

What causes the P00AB code?

• The most common causes of the P00AB code include:
  • Faulty Intake Air Temperature Sensor 1
  • Damaged wiring or connectors in the IAT sensor circuit
  • Issues with the engine control module (ECM)
  • Air intake leaks that affect temperature readings

How to fix P00AB?

• To resolve a P00AB fault code, consider the following steps:
  • Inspect and replace the Intake Air Temperature Sensor 1 if it's found to be faulty.
  • Check for damaged wires or connectors in the IAT sensor circuit and repair any issues.
  • Inspect the air intake system for leaks that could cause erroneous temperature readings.
  • Clear the fault code from the ECM and perform a test drive to see if the code returns.
