P227E 2014 Chevrolet Silverado Code - Barometric Pressure Sensor 2 Circuit Erratic
Quick Answer
The Barometric Pressure (BARO) Sensor 2, also referred to as the Turbocharger Inlet Air Pressure (TCIAP) sensor, is integral to the Multifunction Intake Air Sensor and is used for humidity sensor signal correction. Common causes include Faulty Multifunction Intake Air Sensor, Multifunction Intake Air Sensor harness is open or shorted, Multifunction Intake Air Sensor circuit poor electrical connection. 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.

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.
