Nissan P1105 Code: Manifold Absolute Pressure/Barometric Pressure Switch Solenoid Valve
The P1105 code in Nissan vehicles refers to a problem with the Manifold Absolute Pressure (MAP) sensor or the Barometric Pressure (BARO) switch solenoid valve. The MAP sensor measures the pressure inside the intake manifold, while the BARO switch solenoid valve controls the pressure in the fuel tank. When the engine control module (ECM) detects a malfunction in either of these components, it triggers the P1105 code and illuminates the check engine light. This can cause a variety of issues, including poor fuel economy, rough idling, and reduced engine performance.
To fix the P1105 code, the first step is to diagnose the root cause of the problem. This may involve checking the wiring and connections to the MAP sensor and BARO switch solenoid valve, as well as testing the components themselves. Depending on the severity of the issue, the solution may involve replacing one or both of these parts, or repairing any damaged wiring or connections. It is important to address the P1105 code promptly to prevent further damage to the engine and ensure optimal performance and fuel efficiency.

The P1105 code in Nissan vehicles indicates a problem with the Manifold Absolute Pressure/Barometric Pressure Switch Solenoid Valve. This valve is responsible for regulating the pressure in the intake manifold, which affects the engine’s performance. When this valve fails, it can cause a variety of issues, including poor fuel economy, rough idling, and reduced power.
Here are some of the possible causes of the P1105 code:
- Faulty Solenoid Valve: The most common cause of the P1105 code is a faulty solenoid valve. Over time, the valve can become clogged with debris or fail due to wear and tear. When this happens, it can cause a loss of pressure in the intake manifold, leading to engine performance issues.
- Wiring Issues: Another possible cause of the P1105 code is wiring issues. If the wiring to the solenoid valve is damaged or corroded, it can cause a loss of signal to the valve, leading to engine performance issues.
- Failed Pressure Sensor: In some cases, the P1105 code can be caused by a failed pressure sensor. The pressure sensor is responsible for monitoring the pressure in the intake manifold and sending a signal to the solenoid valve to regulate the pressure. If the sensor fails, it can cause a loss of pressure in the intake manifold, leading to engine performance issues.
- Vacuum Leaks: Vacuum leaks can also cause the P1105 code. If there is a leak in the vacuum system, it can cause a loss of pressure in the intake manifold, leading to engine performance issues.
- Faulty PCM: In rare cases, the P1105 code can be caused by a faulty Powertrain Control Module (PCM). The PCM is responsible for regulating the solenoid valve and monitoring the pressure in the intake manifold. If the PCM fails, it can cause a loss of pressure in the intake manifold, leading to engine performance issues.
