Code P227E 2014 Chevrolet Silverado Description
The P227E diagnostic trouble code (DTC) for a 2014 Chevrolet Silverado indicates an issue with the Barometric Pressure Sensor 2 Circuit being erratic. The barometric pressure sensor is a crucial component of the vehicle's engine management system, responsible for measuring the atmospheric pressure and providing this data to the engine control module (ECM). The ECM uses this information to adjust fuel delivery and ignition timing for optimal engine performance and emissions control.
Common Causes of P227E 2014 Chevrolet Silverado
- Faulty barometric pressure sensor
- Damaged wiring or connectors in the sensor circuit
- ECM software or hardware issues
- Environmental factors affecting sensor readings
- Poor quality fuel or contaminated air intake
Symptoms of P227E 2014 Chevrolet Silverado
- Decreased fuel efficiency
- Rough idling or stalling
- Hesitation or jerking during acceleration
- Engine misfires
- Loss of power and responsiveness
How to Fix P227E 2014 Chevrolet Silverado
- Begin by conducting a thorough inspection of the barometric pressure sensor and its wiring and connectors for any visible damage or corrosion.
- Test the sensor using a multimeter to check for proper voltage and resistance readings.
- If the sensor is faulty, replace it with a new, OEM-quality sensor.
- Clear the DTC from the ECM using a diagnostic scan tool and perform a test drive to ensure the issue has been resolved.
- If the problem persists, further diagnostic testing may be necessary to identify any underlying ECM or wiring issues.

Frequently Asked Questions about P227E 2014 Chevrolet Silverado Code
1. What does the OBDII code P227E mean on a 2014 Chevrolet Silverado?
P227E indicates that the Barometric Pressure Sensor 2 is sending erratic or inconsistent signals to the engine control module (ECM).
2. What are the common symptoms of code P227E?
Symptoms may include poor engine performance, reduced fuel efficiency, rough idling, difficulty starting the engine, and an illuminated check engine light.
3. What causes the P227E code to appear?
Common causes include a faulty barometric pressure sensor, damaged wiring or connectors, a malfunctioning ECM, or environmental factors such as extreme weather conditions.
4. How do I diagnose the P227E code?
Start by using a scan tool to confirm the code, then inspect the barometric pressure sensor, wiring, and connectors for damage or loose connections. Compare sensor readings to known good values.
5. Where is the Barometric Pressure Sensor 2 located on a 2014 Chevrolet Silverado?
The Barometric Pressure Sensor 2 is typically located near the intake manifold or integrated into the ECM, depending on the engine configuration.
6. Can I drive my 2014 Chevrolet Silverado with a P227E code?
While the truck may still run, driving with this code can lead to poor performance and potential damage to the engine if not addressed promptly.
7. How do I fix the P227E code?
Repairs may include replacing the barometric pressure sensor, repairing or replacing damaged wiring or connectors, or updating/reprogramming the ECM if necessary.
8. How much does it cost to fix a P227E code on a 2014 Chevrolet Silverado?
Costs vary, but replacing a barometric pressure sensor typically ranges from $100 to $300, including parts and labor. Wiring repairs or ECM programming may add to the cost.
9. Can a dirty air filter cause the P227E code?
While unlikely, a severely clogged air filter can indirectly affect sensor readings. It’s good practice to check and replace the air filter if needed.
10. Does the P227E code require ECM replacement?
In most cases, no. ECM replacement is only necessary if the ECM itself is diagnosed as faulty after ruling out issues with the sensor and wiring.
