P0108 2014 Chevrolet Silverado Code - Manifold Absolute Pressure/Barometric Pressure Circuit High Input
Quick Answer
The P0108 diagnostic trouble code (DTC) for a 2014 Chevrolet Silverado indicates a problem with the Manifold Absolute Pressure (MAP) sensor or Barometric Pressure (BARO) sensor circuit having a high input. Common causes include Faulty MAP Sensor: The MAP sensor may be malfunctioning, providing incorrect pressure readings to the ECM, Faulty BARO Sensor: The BARO sensor may be sending high input signals due to a fault, Wiring Issues: Wiring harness problems, such as shorts or opens, can disrupt the signal between the sensors and the ECM. 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 P0108 2014 Chevrolet Silverado Description
The P0108 diagnostic trouble code (DTC) for a 2014 Chevrolet Silverado indicates a problem with the Manifold Absolute Pressure (MAP) sensor or Barometric Pressure (BARO) sensor circuit having a high input. The MAP sensor measures the pressure within the intake manifold, providing crucial data to the engine control module (ECM) for fuel delivery and ignition timing. The BARO sensor, on the other hand, measures atmospheric pressure to adjust fuel delivery at different altitudes.
Common Causes of P0108 2014 Chevrolet Silverado
- Faulty MAP Sensor: The MAP sensor may be malfunctioning, providing incorrect pressure readings to the ECM.
- Faulty BARO Sensor: The BARO sensor may be sending high input signals due to a fault.
- Wiring Issues: Wiring harness problems, such as shorts or opens, can disrupt the signal between the sensors and the ECM.
- Vacuum Leak: A leak in the intake system can affect pressure readings and trigger this code.
- ECM Malfunction: In rare cases, a problem with the engine control module itself can cause high input signals from the sensors.
Symptoms of P0108 2014 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Reduced Engine Power: The vehicle may experience a loss of power during acceleration or while driving.
- Rough Idle: The engine may idle roughly or inconsistently, causing vibrations or shaking.
- Poor Fuel Efficiency: The vehicle may consume more fuel than usual due to incorrect fuel and air mixture.
- Emissions Issues: The vehicle may fail emissions tests due to increased emissions caused by the faulty sensor readings.
How to Fix P0108 2014 Chevrolet Silverado
- Diagnostic Scan: Use an OBD-II scanner to retrieve the trouble code and confirm the issue with the MAP or BARO sensor.
- Sensor Inspection: Inspect the MAP and BARO sensors for any visible damage or signs of malfunction.
- Wiring Check: Inspect the wiring harness for any damage, corrosion, or loose connections that may be affecting sensor signals.
- Vacuum Leak Test: Perform a smoke test or visual inspection to check for any leaks in the intake system.
- Sensor Replacement: If the sensors are faulty, replace them with OEM or high-quality aftermarket parts to ensure proper function.
Cost to Fix P0108 2014 Chevrolet Silverado
The cost of repairing a P0108 code on a 2014 Chevrolet Silverado can vary depending on the specific cause of the issue. Typically, the cost of replacing a MAP or BARO sensor ranges from $50 to $200 per sensor, excluding labor costs. The total repair cost, including parts and labor, can range from $150 to $500. It's important to note that diagnostic time and labor rates at auto repair shops can vary, so it's advisable to check with local shops for a more accurate estimate.

Frequently Asked Questions about P0108 2014 Chevrolet Silverado Code
1. What does the OBDII code P0108 mean on a 2014 Chevrolet Silverado?
P0108 indicates that the Manifold Absolute Pressure (MAP) sensor is reporting a voltage signal that is higher than the expected range, suggesting a potential issue in the MAP/Barometric Pressure circuit.
2. What are common symptoms of code P0108 in a 2014 Chevrolet Silverado?
Common symptoms include poor engine performance, rough idling, difficulty starting, reduced fuel efficiency, black smoke from the exhaust, and the illumination of the Check Engine Light.
3. What causes the P0108 code to appear on a 2014 Chevrolet Silverado?
Possible causes include a faulty MAP sensor, damaged wiring or connectors in the MAP sensor circuit, vacuum leaks, a clogged air filter, or issues with the engine control module (ECM).
4. How do you diagnose the P0108 code on a 2014 Chevrolet Silverado?
Start by inspecting the MAP sensor and its wiring for damage or loose connections. Use a scan tool to check live data from the MAP sensor and compare it to manufacturer specifications. Test for vacuum leaks and ensure the sensor is receiving proper voltage.
5. Can a faulty MAP sensor cause the P0108 code on a 2014 Chevrolet Silverado?
Yes, a faulty MAP sensor that sends incorrect voltage signals to the ECM is a common cause of the P0108 code.
6. How can I fix the P0108 code on my 2014 Chevrolet Silverado?
Repairs may include replacing the MAP sensor, repairing or replacing damaged wiring, fixing vacuum leaks, or cleaning a clogged air filter. If necessary, reprogramming or replacing the ECM may be required.
7. Is it safe to drive a 2014 Chevrolet Silverado with a P0108 code?
While the vehicle may still be drivable, driving with a P0108 code can lead to poor engine performance, increased fuel consumption, and potential damage to other components. It’s best to address the issue promptly.
8. How much does it cost to repair a P0108 code on a 2014 Chevrolet Silverado?
Repair costs can vary but typically include $75-$125 for a MAP sensor replacement and additional labor charges if wiring repairs or diagnostics are needed. Total costs depend on the specific issue.
9. Can a dirty air filter trigger the P0108 code on a 2014 Chevrolet Silverado?
Yes, a clogged or dirty air filter can restrict airflow and potentially lead to incorrect readings from the MAP sensor, which could trigger the P0108 code.
10. Do I need to clear the P0108 code after repairs on a 2014 Chevrolet Silverado?
Yes, after completing repairs, use an OBDII scan tool to clear the code and reset the Check Engine Light. Drive the vehicle to ensure the issue is resolved and the code does not return.
