What does the code P2070 mean?
intake manifold tuning
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 P2078?
What repairs can fix the P2078 code?
- Replacing the IMT valve (the sensor that this code indicates is the problem is most often part of the IMT valve assembly and will be replaced as a single unit)
- Repairing wiring to the control circuit.
- Repairing vacuum lines that may be plugged or leaking.
What is an intake manifold tuning valve?
The intake manifold tuning valve comes with many possible purposes to help the engine in both performance and drivability. It regulates the pressure between intake plenums, or redirect intake air to separate set of intake runners (or combination) to change the flow and possibly the performance of the engine.
What is code P2017?
The runner position sensor, also known as the runner valve, controls the volume of air entering the intake manifold. If code P2017 sets, it indicates that the runner valve is not closing and opening as required by the Engine Control Module (ECM); the correlation between the ECM and runner valve is out of sequence.
What does p2070 stand for in OBD code?
P2070 is a diagnostic trouble code (DTC) for “Intake Manifold Tuning (IMT) Valve Stuck Open”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $0.0 .
Where is DTC p2070 located on a GMC Uplander?
Using a Tech 2 you may find that there is DTC P2070 or P2071 or P2077 or P2078 stored in the Powertrain Control Module (PCM). The bushing located inside the upper intake manifold that supports the tip of the intake manifold tuning valve shaft may be missing.
What does stored code p2070 mean on a Honda Accord?
A stored code P2070 means that the powertrain control module (PCM) has detected an intake manifold tuning (IMT) valve that is stuck open for engine bank two. Bank 1 refers to the bank of the engine which contains the number one cylinder. Intake manifold tuning is used to restrict and control intake air as it enters individual manifold ports.
What kind of diagnostic scanner do I need for p2070?
A diagnostic scanner, a digital volt/ohmmeter (DVOM), and a source of vehicle specific diagnostic information will be required to diagnose a code P2070.
