OBD-II Generic Error Code P0095: How to Fix It

Q: What does OBD-II code P0095 mean?

P0095 means the engine control module (ECM) has detected a malfunction in the Intake Air Temperature (IAT) Sensor 2 circuit. This sensor measures the temperature of the air entering the engine to help adjust fuel and timing.

Q: Can I drive my car with a P0095 code?

You can usually drive for short distances, but the engine may run poorly, especially in cold weather or under load. Prolonged driving with this code can lead to reduced fuel economy and potential damage to the catalytic converter. It's best to diagnose and fix it promptly.

Q: What are the symptoms of a bad IAT sensor 2?

Symptoms include a check engine light, poor engine performance, hard starting in cold weather, rough idle, reduced fuel economy, and sometimes black smoke from the exhaust.

Q: Where is the IAT sensor 2 located?

The IAT sensor 2 is typically located in the intake air duct after the intercooler (on turbocharged engines) or after the air filter housing. On some vehicles, it may be integrated into the mass airflow (MAF) sensor or mounted in the intake manifold. Check your service manual for exact location.

Q: How much does it cost to fix code P0095?

The cost varies by vehicle but typically ranges from $50 to $200 for the sensor plus diagnostic time if done by a shop. DIY can be as low as $20-50 for the part.

Abstract

Error code P0095 indicates a problem with the Intake Air Temperature (IAT) Sensor 2 circuit. This sensor tells the engine computer the temperature of the air entering the engine. When the circuit fails or the sensor gives an out-of-range reading, the check engine light turns on and the engine may run poorly, especially during cold starts or hard acceleration.
