P112E Code - Manifold Absolute Pressure To Throttle Angle Too Low Bank 1
Quick Answer
The Manifold Absolute Pressure (MAP) sensor is used to monitor engine load by sampling the depression in the inlet manifold. Common causes include Faulty Intake Pipe Vacuum Sensor, Intake Pipe Vacuum Sensor harness is open or shorted, Intake Pipe Vacuum Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P112E Description
The signal from the MAP sensor can be used for calculating the fuel injection quantity, rate of ignition advance or retard, boost pressure control, and idle speed control.
The Digital Motor Electronics (DME) diagnosis monitors the plausible position of the throttle valve in relation to the applied intake pipe vacuum. The Diagnostic Trouble Code (DTC) is detected when the ascertained air mass flow falls below a limit value.
What are the Possible Causes of the DTC P112E?
- Faulty Intake Pipe Vacuum Sensor
- Intake Pipe Vacuum Sensor harness is open or shorted
- Intake Pipe Vacuum Sensor circuit poor electrical connection
- Faulty Electromotive Throttle Actuator
How to Fix the DTC P112E?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P112E code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
