The factors influencing the cost of diagnosing and fixing the automobile fault code p1104 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 p1104 fault code.

The P1104 fault code indicates a low voltage reading from the Manifold Absolute Pressure (MAP) sensor in the engine’s Engine Control Module (ECM). The MAP sensor provides important information about the manifold pressure to the ECM, which is used to calculate air density and determine the engine’s air mass flow rate.

This data is crucial for determining the required fuel metering for optimal combustion. In simpler terms, the MAP sensor helps the engine control system understand how much air is entering the engine. This information is used to ensure the right amount of fuel is injected for efficient combustion.

When the ECM detects a low voltage reading from the MAP sensor, it triggers the P1104 fault code.

This code indicates that there may be an issue with the MAP sensor or its electrical connection, which can affect the engine’s performance and fuel efficiency. It is important to address this issue promptly to avoid further damage to the engine.

What are the possible causes for the automobile fault code p1104?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P1104 could be the culprit. 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 the issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Don’t forget to check the possible causes listed above for a more comprehensive solution.

How can I visually inspect the wiring harness and connectors to fix the p1104 fault code?

If you’re dealing with the p1104 fault code and your engine light is on, it’s time to take action. The culprit could be a faulty Manifold Absolute Pressure (MAP) or an issue with the wiring harness and connectors. To fix it, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken or bent pins, corrosion, or components that are out of place. This simple step could be the key to resolving the issue and getting your engine running smoothly again.

What should I look for when checking for damaged components and connector’s pins to resolve the p1104 fault code?
