P1192 RAM Code - Inlet Air Temperature Sensor Circuit Low Condition
Quick Answer
The P1192 diagnostic trouble code (DTC) refers to a fault in the Inlet Air Temperature Sensor (IAT) circuit, indicating that the voltage signal from the sensor is lower than the expected range. Common causes include Faulty Inlet Air Temperature Sensor, Damaged wiring or connectors in the sensor circuit, Corrosion or contamination in the sensor connector. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1192 RAM Description
The P1192 diagnostic trouble code (DTC) refers to a fault in the Inlet Air Temperature Sensor (IAT) circuit, indicating that the voltage signal from the sensor is lower than the expected range. The IAT sensor plays a crucial role in monitoring the temperature of the incoming air into the engine. This data is vital for the Engine Control Module (ECM) to adjust the air-fuel mixture and ignition timing for optimal engine performance and efficiency.
Common Causes of P1192 RAM
- Faulty Inlet Air Temperature Sensor
- Damaged wiring or connectors in the sensor circuit
- Corrosion or contamination in the sensor connector
- ECM malfunction
- Intake air leaks
Symptoms of P1192 RAM
- Reduced fuel efficiency
- Engine misfires
- Rough idling
- Check Engine Light illuminated
- Engine performance issues
How to Fix P1192 RAM
- Begin by visually inspecting the wiring and connectors in the IAT sensor circuit for any signs of damage or corrosion.
- Test the IAT sensor using a multimeter to check for proper resistance values and voltage output.
- Replace the IAT sensor if it is found to be faulty.
- Clear the DTC using an OBD-II scanner and test drive the vehicle to ensure the code does not return.
- If the issue persists, further diagnostic testing may be necessary to identify any underlying electrical faults or ECM issues.
Cost to Fix P1192 RAM
The cost to repair a P1192 RAM code related to the Inlet Air Temperature Sensor Circuit Low Condition can vary depending on the specific cause of the issue. On average, the cost of replacing a faulty IAT sensor ranges from $50 to $150, with additional costs for labor at an average of $80 to $150 per hour. If wiring or connectors need to be repaired or replaced, the total cost may increase. It is advisable to consult with a professional mechanic for an accurate diagnosis and repair estimate.

Frequently Asked Questions about P1192 RAM Code
What does the OBDII code P1192 mean on a RAM vehicle?
P1192 indicates an "Inlet Air Temperature Sensor Circuit Low Condition," meaning the voltage from the inlet air temperature (IAT) sensor is lower than expected by the engine control module (ECM).
What are common symptoms of a P1192 code on a RAM?
Symptoms may include poor engine performance, reduced fuel efficiency, difficulty starting, and the check engine light illuminating.
What causes the P1192 code to appear?
Common causes include a faulty inlet air temperature sensor, damaged or corroded wiring, a poor electrical connection, or a malfunctioning ECM.
Can a dirty air filter cause the P1192 code?
No, a dirty air filter is unlikely to cause this code. The issue is typically electrical or sensor-related, not airflow-related.
How do I diagnose the P1192 code?
Start by inspecting the IAT sensor and its wiring for damage or corrosion. Use a multimeter to check sensor resistance and wiring continuity. If these check out, test the ECM.
Can I drive with a P1192 code?
While driving with a P1192 code is possible, it’s not recommended, as it can lead to poor engine performance and potential long-term damage.
How do you fix the P1192 code on a RAM vehicle?
Repairs may involve replacing the IAT sensor, repairing or replacing damaged wiring or connectors, or, in rare cases, replacing the ECM.
What tools are needed to troubleshoot a P1192 code?
You will need an OBDII scanner, a multimeter, and possibly a repair manual for your specific RAM model to locate components and wiring diagrams.
How much does it cost to fix a P1192 code?
Repair costs can range from $50 to $200, depending on whether the issue is a simple sensor replacement or involves wiring repairs.
Can extreme weather cause a P1192 code?
Yes, extreme cold or heat can sometimes affect sensor performance or wiring, potentially triggering this code.
