P0095
Fix within a few daysYour engine's computer isn't getting a proper signal from the Intake Air Temperature (IAT) Sensor 2. This sensor measures the temperature of the air entering your engine after the turbocharger or supercharger, or in a secondary intake path.
Code P0095 means your Intake Air Temperature Sensor 2 circuit has a problem. Common causes: Bad IAT Sensor 2 (80%), wiring issues (15%). Drivability: Yes, safe to drive, but fix soon. Repair cost: $30-$100 DIY, $100-$250 professional.
Can I Drive With P0095?

A rare internal fault in the engine computer prevents it from correctly reading the IAT Sensor 2 signal.
5% of P0095 cases are fixed by replacing the ECM/PCM
Check These First (Before Buying Parts)
- Visually inspect the IAT Sensor 2 and its electrical connector for any visible damage, corrosion, or loose wires.
- Ensure the sensor is securely plugged in.
- Clear the code with an OBD-II scan tool and see if it immediately returns after starting the engine.
How to Diagnose P0095
- 1Visually inspect the IAT Sensor 2 and its wiring for any obvious damage, corrosion, or loose connections.
- 2Using a multimeter, test the resistance of the IAT Sensor 2 at various temperatures (if possible) to check for proper operation.
- 3Check for proper voltage supply and ground at the IAT Sensor 2 connector using a multimeter.
- 4Use a scan tool to monitor the live data for IAT Sensor 2. Compare its reading to ambient air temperature when the engine is cold.
- 5If the sensor and wiring check out, consider testing the continuity of the sensor circuit back to the ECM/PCM.
P0095 on Popular Vehicles
Ford F-150
2011-2024EcoBoost engines often have multiple IAT sensors. P0095 on these models frequently indicates a failed IAT Sensor 2, which is typically located after the intercooler or in the charge air cooler pipe. These sensors can be prone to failure due to heat and pressure.
85% fixed by replacing IAT Sensor 2
Chevrolet Silverado
2014-2024Some newer Silverado models, particularly those with forced induction or specific intake designs, use multiple IAT sensors. P0095 can be triggered by a faulty sensor or, less commonly, by wiring damage near the intake manifold or turbocharger components.
75% fixed by replacing IAT Sensor 2
Honda Accord
2018-2024Turbocharged Honda Accord models may utilize multiple IAT sensors. P0095 can occur due to sensor failure or, in some cases, a loose or corroded connection to the sensor, especially if the vehicle has been exposed to harsh weather or engine bay cleaning.

Frequently Asked Questions
What does P0095 mean?
P0095 indicates that your vehicle's engine computer has detected an electrical fault in the circuit for Intake Air Temperature (IAT) Sensor 2. This sensor measures the temperature of the air entering the engine, often after a turbocharger or in a secondary intake path.
Can I drive with P0095?
Yes, you can drive with P0095, but fix it within a few days. Your engine's performance and fuel economy will suffer, and it can lead to higher emissions. Continued driving with an incorrect air temperature reading can cause the engine to run too rich or too lean, which is not ideal for long-term engine health.
Will P0095 clear itself?
No, P0095 will not clear itself. The engine computer stores this code because it detects a persistent electrical fault. You must diagnose and repair the underlying issue, then clear the code with an OBD-II scan tool.
How do I fix P0095 myself?
Start by visually inspecting the IAT Sensor 2 and its wiring for damage. If the wiring looks good, test the sensor's resistance with a multimeter. If the sensor is faulty, replace it. If the sensor tests good, check the wiring for continuity and voltage at the connector.
How much does it cost to fix P0095?
A DIY fix for P0095 typically costs $30-$100 for a new IAT Sensor 2. If you take it to a professional shop, expect to pay $100-$250, which includes parts and labor.
P0095 keeps coming back - why?
If P0095 keeps returning, it means the root cause was not fully addressed. This often points to an intermittent wiring issue that was missed, a faulty connector, or a rare ECM/PCM problem. Double-check all wiring and connections thoroughly, and ensure the replacement sensor is functioning correctly.
Will P0095 fail emissions/smog test?
Yes, P0095 will cause your vehicle to fail an emissions or smog test. A Check Engine Light indicates an active fault in the emissions system, and the vehicle will not pass inspection until the code is cleared and monitors are set.
What's the difference between P0095 and P0096?
P0095 indicates a general electrical circuit malfunction for IAT Sensor 2, meaning the computer isn't getting a valid signal at all. P0096 indicates an IAT Sensor 2 'Range/Performance' problem, meaning the sensor is sending a signal, but it's outside the expected operating range or inconsistent with other sensor readings.
P0095 on Ford F-150?
On Ford F-150s, especially EcoBoost models with multiple IAT sensors, P0095 often points directly to a faulty IAT Sensor 2. These sensors can fail due to heat or contamination. Always verify the specific location of Sensor 2, as it's typically post-intercooler or in a secondary intake runner.
Questions to Ask Your Mechanic
Did you check the live data for IAT Sensor 2 with a scan tool?
Good answer: Yes, the live data showed a constant -40°F reading, indicating an open circuit, or a fixed high temperature, indicating a short. This confirms the sensor or its circuit is faulty.
What were the voltage readings at the IAT Sensor 2 connector?
Good answer: I checked the connector. I have 5 volts on the reference wire and a good ground, so the problem is either the sensor itself or the signal wire back to the ECM.

Cost of Waiting
Ignoring P0095 leads to reduced fuel economy and poor engine performance. The engine computer will use a default value, which is not accurate, causing the engine to run too rich or too lean. This can increase harmful emissions and, over time, potentially damage other components like your catalytic converter ($800-$2,500 repair). A $30-$100 sensor fix now prevents a much larger bill later.
While You're In There...
If the IAT sensor is located near the air filter housing, replacing a dirty air filter ensures optimal airflow and prevents future sensor contamination.
If your IAT sensor is integrated into the MAF sensor or located nearby, cleaning the MAF sensor can address related airflow issues and is a quick, inexpensive maintenance step.

Your Next Steps
Step 1: Visually inspect the IAT Sensor 2 and its wiring for any obvious damage, corrosion, or loose connections. Ensure the connector is fully seated.
Step 2: If the visual inspection doesn't reveal the problem, use a multimeter to test the resistance of the IAT Sensor 2. Compare the readings to your vehicle's service manual specifications.
Step 3: If the sensor tests faulty, replace it. If the sensor tests good, use the multimeter to check for proper voltage supply and ground at the sensor connector. If voltage or ground is missing, trace the wiring back to the ECM/PCM for damage.
