P1160 Volkswagen Code - Intake Air Temperature Sensor Short To Ground
Quick Answer
The P1160 diagnostic trouble code for Volkswagen vehicles indicates that there is a short to ground in the intake air temperature (IAT) sensor circuit. Common causes include Wiring Damage: The wiring harness connecting the intake air temperature sensor to the ECM may be damaged or frayed, leading to a short to ground, Sensor Failure: The intake air temperature sensor itself may be faulty or damaged, causing a short circuit, Corrosion: Corrosion or moisture intrusion in the sensor or wiring connections can also lead to a short to ground. 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 P1160 Volkswagen Description
The P1160 diagnostic trouble code for Volkswagen vehicles indicates that there is a short to ground in the intake air temperature (IAT) sensor circuit. The intake air temperature sensor is a crucial component of the engine management system, as it measures the temperature of the air entering the engine. This information is used by the engine control module (ECM) to adjust fuel injection and ignition timing for optimal performance and fuel efficiency.
Common Causes of P1160 Volkswagen
- Wiring Damage: The wiring harness connecting the intake air temperature sensor to the ECM may be damaged or frayed, leading to a short to ground.
- Sensor Failure: The intake air temperature sensor itself may be faulty or damaged, causing a short circuit.
- Corrosion: Corrosion or moisture intrusion in the sensor or wiring connections can also lead to a short to ground.
- ECM Malfunction: A malfunctioning ECM could also be the root cause of the issue, disrupting the communication with the intake air temperature sensor.
- Poor Electrical Ground: A poor electrical ground connection in the sensor circuit can cause a short to ground.
Symptoms of P1160 Volkswagen
- Check Engine Light: The most common symptom of this code is the illumination of the check engine light on the dashboard.
- Reduced Engine Performance: The vehicle may experience a decrease in power and acceleration due to incorrect fuel mixture adjustments.
- Poor Fuel Efficiency: A shorted intake air temperature sensor can lead to inefficient fuel combustion, resulting in decreased fuel economy.
- Rough Idling: The engine may run rough or have unstable idling due to incorrect air-fuel mixture ratios.
- Emission Issues: The vehicle may fail emissions tests or produce higher emissions than normal due to the malfunctioning sensor.
How to Fix P1160 Volkswagen
- Diagnose the Issue: Use a diagnostic scanner to retrieve the fault code and perform further testing to pinpoint the exact cause of the short to ground.
- Inspect Wiring: Check the wiring harness for any signs of damage, corrosion, or poor connections. Repair or replace any damaged wiring as needed.
- Test the Sensor: Test the intake air temperature sensor for proper operation using a multimeter. Replace the sensor if it is found to be faulty.
- Check ECM: Inspect the ECM for any signs of damage or malfunction. Repair or replace the ECM if necessary.
- Clear Codes: Clear the fault codes from the ECM memory after completing the repairs and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P1160 Volkswagen
The cost of repairing a P1160 code for a Volkswagen vehicle can vary depending on the specific cause of the issue and the labor rates in your area. Typically, the cost of parts for replacing an intake air temperature sensor can range from $50 to $150, while labor costs can range from $100 to $200. However, additional costs may apply if wiring repairs or ECM replacement are necessary. It's recommended to consult with a qualified mechanic or repair shop for a more accurate cost estimate based on your vehicle's specific needs. Labor rates at auto repair shops can vary between $80 and $150 per hour, so it's advisable to inquire about rates in your area before proceeding with the repairs.
