Volvo Land Rover Error Code P1106: How to Fix It

Q: Can I drive with error code P1106?

Yes, this is a low-severity code. However, you may notice reduced fuel economy or slightly rough idle. It's safe to drive short distances, but you should address it soon.

Q: What is a BARO sensor?

The BARO sensor measures barometric (atmospheric) pressure. The ECM uses this data to adjust air-fuel mixture and ignition timing for optimal performance at different altitudes.

Q: Does altitude affect the BARO sensor reading?

Yes, the BARO sensor voltage decreases with altitude. At sea level, voltage is around 4.5-5V; at high altitude, it can drop to 3V or less. This is normal and not a fault.

Q: Will clearing the code fix the problem permanently?

Clearing the code only erases the stored fault. If the underlying issue (e.g., faulty sensor or wiring) is not fixed, the code will return.

Q: Where is the BARO sensor located on Volvo/Land Rover?

Common locations include on the intake manifold, near the throttle body, or mounted on the firewall. Check your vehicle's service manual for exact location.

Abstract

Error code P1106 in Volvo and Land Rover vehicles indicates that the Barometric Pressure (BARO) sensor circuit is experiencing a range or performance issue. This sensor measures atmospheric pressure to help the engine control module (ECM) adjust fuel delivery and ignition timing. While this code is low severity, it can affect engine performance and fuel economy.
