The factors influencing the cost of diagnosing and fixing the automobile fault code p1103 include the estimated repair time of 1.0 hour.

Most auto repair shops typically charge between $75 and $150 per hour for their services. These factors contribute to the overall cost of resolving the p1103 fault code.

The P1103 fault code indicates a high voltage reading from the Manifold Absolute Pressure (MAP) sensor in the engine’s Engine Control Module (ECM).

The MAP sensor provides real-time information about the pressure in the engine’s intake manifold, which is used to calculate air density and determine the engine’s air mass flow rate.

This information is crucial for the ECM to accurately meter the fuel for optimal combustion. In simpler terms, the MAP sensor helps the engine control system determine how much fuel to inject into the engine based on the amount of air entering the intake manifold. A high voltage reading from the MAP sensor can disrupt this calculation, leading to potential issues with fuel metering and combustion efficiency.

It is important to address this fault code promptly to ensure the engine operates at its best performance and fuel efficiency.

What are the possible causes for the automobile fault code p1103?

If you see the engine light on or the service engine soon warning light, it could be due to fault code P1103. This code is often caused by a faulty Manifold Absolute Pressure (MAP) sensor, an open or shorted MAP harness, a poor electrical connection in the MAP circuit, or a faulty Engine Control Module (ECM). To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look out for broken, bent, pushed out, or corroded pins in the connectors.

How can I visually inspect the wiring harness and connectors to fix the p1103 fault code?

If you’re dealing with the p1103 fault code and your engine light is on, it’s time to take action.
