What the P2070 code means. When trouble code P2070 sets, the engine control unit (ECU) has determined that the intake manifold tuning (IMT) valve is stuck open. The ECU gets this information from a position sensor that is built into the tuning valve actuator.
How do I fix code P2070?
How To Correct P2070 Intake Manifold Tuning (IMT) Valve Stuck Open Bank 1
- Repair or replace the faulty Intake Manifold Tuning Valve Position Sensor.
- Repair or replace the faulty Intake Manifold Tuning Valve Position Switch.
- Repair or replace the faulty Intake Manifold Tuning Valve (IMTV)
What is an IMT valve?
An actuator for an intake manifold tuning valve to regulate airflow in an intake manifold of an internal combustion engine. The actuator includes a motor, control circuit, and sensor all mounted in a housing that has an opening through which an output shaft extends.
What is an intake manifold tuning valve?
The intake manifold tuning valve opens and closes the flap in your intake manifold. It regulates the pressure between intake plenums and is also responsible for redirecting air to the right intake runners, aiding in driveability and engine performance.
How do I fix code P0661?
What repairs can fix the P0661 code?
- Reinstalling the driver in the PCM.
- Replacing a failed intake manifold tuning valve.
- Repairing loose or corroded connections in the wiring for the intake manifold tuning valve.
What causes P2070 code?
What the P2070 code means. When trouble code P2070 sets, the engine control unit (ECU) has determined that the intake manifold tuning (IMT) valve is stuck open. The ECU gets this information from a position sensor that is built into the tuning valve actuator.
What is code P2078?
P2078 is a diagnostic trouble code (DTC) for “Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit High“. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What can a bad intake manifold runner control cause?
If the intake manifold runner control has an issue it can cause the vehicle to experience engine performance issues such as misfires, a decrease in power and acceleration, a decrease in fuel efficiency, and even stalling.
How much does it cost to replace a intake manifold runner control?
A new intake manifold runner valve can cost anywhere between $50 and $200, depending on factors like its brand and your vehicle’s specifications. Labor costs for replacing a damaged intake manifold runner valve typically range from $300 to $400.
