What is P2229 : Engine Error code Causes Explained
This Guide covers the P2229 engine trouble code, its causes, and its effects on vehicle performance. Poor fuel economy, rough idling, and engine reluctance might result from this code’s excessive barometric pressure sensor circuit reading.
How to Identify a DTCs Number
The Diagnostic Trouble Code (DTC) P2229 refers to a high input signal from the Barometric Pressure (BARO) sensor.
Understand, this trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
This can occur due to a faulty sensor, wiring issues, or an ECM malfunction. To identify a P2229 engine error code, you will need an OBD-II scanner.
Causes of P2229 Code:
- Damaged barometric pressure sensor:
The sensor may be damaged or malfunctioning - Electrical connector issues:
The electrical connector may be defective or have an imperfect connection - Wiring problems:
The wiring may be flawed or have an internal or mechanical short - Faulty engine control module:
The engine control module may be faulty - Heat damage:
The sensor may be damaged due to heat.
Risk Level of P2229 Error Code:
The P2229 engine error code indicates a Barometric Pressure Sensor “A” Circuit High issue. A high-risk level means it can cause engine performance problems, such as rough idling, poor acceleration, or even stalling.
Immediate inspection and repairs are strongly recommended to prevent further damage and ensure vehicle safety.

- Mercedes-Benz
- Mazda
- Saab
- BMW
- Acura
- chevrolet
- GMC
- Honda
- Volswagen
- Volvo
