This summary uses the existing diagnostic information shown in full below.
This code means that the sensor that checks the air pressure going into the turbocharger or supercharger is not working properly all the time. It's like a thermometer that sometimes shows the wrong temperature.
The P012E code is triggered when the Powertrain Control Module (PCM) detects an intermittent or erratic signal from the turbocharger or supercharger inlet pressure sensor.
The turbocharger/supercharger inlet pressure sensor measures the pressure of the air entering the turbocharger or supercharger. This information is crucial for the PCM to adjust the air-fuel mixture and boost pressure. An intermittent or erratic signal from this sensor can lead to improper engine performance and efficiency.
• Check Engine Light is on
• Poor engine performance
• Reduced fuel efficiency
• Faulty turbocharger/supercharger inlet pressure sensor
• Wiring issues such as frayed wires or poor connections
• Faulty PCM
PCM: Powertrain Control Module, the brain of the vehicle's engine management system.
Turbocharger: A device that increases the engine's efficiency and power output by forcing extra air into the combustion chamber.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections to the sensor.
• Test the sensor with a multimeter for proper operation.
• Replace the faulty pressure sensor.
• Repair or replace damaged wiring or connectors.
• Update or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

• Dodge Ram
• Regular maintenance checks
• Ensure proper electrical connections
• Use quality replacement parts
Sensor Issue
• Do not ignore the Check Engine Light.
• Get the vehicle checked by a professional mechanic.
• Avoid hard driving until the issue is resolved.
Check your vehicle's warranty for coverage on sensor-related repairs.
This code has been more prevalent in turbocharged vehicles as they rely heavily on accurate pressure readings for optimal performance.
Moderate – It should be addressed soon to avoid potential engine performance issues.
Driving with a faulty sensor can lead to decreased engine performance and increased emissions, which may not comply with legal standards.
• Engine running
• Vehicle at operating temperature
The turbocharger/supercharger inlet pressure sensor is typically located near the air intake of the turbocharger or supercharger.
Q: Can I drive my car with a P012E code?
A: It's possible to drive, but it's not recommended as it can lead to poor engine performance and increased fuel consumption.
Q: How do I reset the Check Engine Light after fixing the issue?
A: You can reset the light by using an OBD-II scanner or by disconnecting the battery for a few minutes.
