Check These First (Before Buying Parts)
- Visually inspect the IAT Sensor 2 connector and wiring for any signs of damage, corrosion, or loose connections. Ensure the connector is fully seated.
- Check your air filter. A severely clogged air filter can sometimes affect air flow readings, though less likely for a circuit range code.
How to Diagnose P0096
- 1Visually inspect the IAT Sensor 2 and its wiring harness for any obvious damage, corrosion, or loose connections.
- 2Use a multimeter to test the resistance of the IAT Sensor 2 at various temperatures, comparing readings to manufacturer specifications.
- 3With a scan tool, monitor the live data for IAT Sensor 2. Check if the temperature reading is plausible and changes with engine temperature.
- 4If the sensor tests good, check for continuity and shorts in the wiring between the IAT sensor and the ECM/PCM.
P0096 on Popular Vehicles
Ford F-150
2011-2024Many EcoBoost F-150s use multiple IAT sensors. P0096 usually refers to the sensor located after the turbocharger or in the intake manifold. These sensors can fail due to heat exposure.

Chevrolet Silverado
2014-2024On Silverado models with multiple IAT sensors, P0096 often indicates a problem with the sensor in the intake manifold or charge pipe. Wiring harness damage from rodent activity or chafing is also a known issue.
70% fixed by replacing the IAT Sensor 2
Honda Accord
2013-2024Some Honda Accord models with forced induction or specific engine configurations utilize a second IAT sensor. P0096 on these vehicles is frequently caused by a failing sensor or a corroded electrical connector.

Frequently Asked Questions
What does P0096 mean?
P0096 indicates that your vehicle's engine computer has detected an issue with the Intake Air Temperature (IAT) Sensor 2 circuit, specifically that its readings are outside the expected range or performing incorrectly on Bank 1.
Can I drive with P0096?
Yes, you can drive safely with a P0096 code. The engine computer will use a default value for intake air temperature, which can lead to reduced fuel economy and performance. Fix this within 1-2 weeks to prevent long-term issues.
Will P0096 clear itself?
No, P0096 will not clear itself. The underlying problem, whether it's a faulty sensor or wiring, must be repaired. After the repair, you can clear the code with a scan tool, or it will eventually clear after several drive cycles if the issue is resolved.
How do I fix P0096 myself?
Start by visually inspecting the IAT Sensor 2 and its wiring for damage. If the wiring is good, test the sensor's resistance with a multimeter. If the sensor is faulty, replace it. This usually involves disconnecting the electrical connector and unbolting or unclipping the sensor from the intake system.
How much does it cost to fix P0096?
A DIY fix for P0096 typically costs $20-$80 for a new IAT Sensor 2. If you take it to a professional shop, expect to pay $95-$305, which includes parts and 0.5-1.5 hours of labor.
P0096 keeps coming back - why?
If P0096 keeps returning, it often means the initial diagnosis was incomplete. You might have a persistent wiring issue, a poor connection at the sensor or ECM, or the ECM itself is faulty. Ensure you're replacing the correct IAT sensor (Sensor 2, not Sensor 1).
Will P0096 fail emissions/smog test?
Yes, P0096 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on is an automatic failure in most jurisdictions, and the faulty IAT sensor can lead to incorrect fuel mixture, increasing harmful emissions.
What's the difference between P0096 and P0095?
P0096 indicates a 'Range/Performance' issue with IAT Sensor 2, meaning the sensor's readings are inconsistent or outside expected values. P0095 indicates a 'Circuit Malfunction' for IAT Sensor 2, meaning the engine computer isn't receiving any signal or the circuit is open/shorted.
P0096 on Ford F-150?
On Ford F-150s, especially EcoBoost models, P0096 often points directly to a faulty IAT Sensor 2, which is typically located in the charge air cooler outlet or intake manifold. Wiring issues are also common due to exposure to engine heat and vibrations. Always verify the correct sensor location for your specific engine.
Questions to Ask Your Mechanic
Did you check the live data for IAT Sensor 2 and compare it to IAT Sensor 1 (if applicable) and ambient air temperature?
Good answer: Yes, the IAT Sensor 2 reading was stuck at -40°F (or an implausible high value) while IAT Sensor 1 and ambient were reading correctly. This points to a bad sensor or open circuit.
What did you find when you inspected the wiring harness for the IAT Sensor 2?
Good answer: I found no visible damage, but I performed a wiggle test on the connector and checked for continuity and resistance between the sensor and the ECM, and everything tested good, confirming the sensor itself is faulty.

Cost of Waiting
Ignoring P0096 means your engine runs with an incorrect fuel mixture. This leads to reduced fuel economy, decreased engine power, and increased emissions. Over time, this can cause carbon buildup on valves or even damage to your catalytic converter ($800-$2,500 repair) due to inefficient combustion.
While You're In There...
If you're working near the intake system, it's a good time to check and replace the air filter if it's dirty, as it's a common maintenance item and affects air flow.
While not directly related to IAT Sensor 2, cleaning the MAF sensor (often located nearby in the intake tract) can improve overall air intake accuracy and engine performance.
Tools You'll Need
- OBD-II scan tool
- Multimeter
- Basic hand tools (sockets, wrenches, screwdrivers)
- Electrical contact cleaner (optional)
P0096 is a common sensor code. Most repairs are straightforward, involve replacing an inexpensive part, and your engine will run more efficiently afterward.

Your Next Steps
Step 1: Visually inspect the IAT Sensor 2 and its wiring harness for any obvious damage, corrosion, or loose connections. Clean the connector with electrical contact cleaner if needed.
Step 2: If the visual inspection doesn't reveal the problem, use an OBD-II scan tool to monitor the live data for IAT Sensor 2. Compare its reading to ambient temperature and IAT Sensor 1 (if present). If the reading is implausible or stuck, proceed to sensor testing.
Step 3: If the sensor reading is suspect, disconnect the sensor and test its resistance with a multimeter. Compare the readings to your vehicle's service manual specifications. If the sensor is out of spec, replace it.
