The P2071 fault code in automobiles indicates a problem with the Intake Manifold Tuning Valve (IMTV) or the Intake Manifold Runner Control (IMRC).

The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light. The cause of this fault code could be a faulty IMTV, open or shorted IMTV harness, poor electrical connection in the IMTV circuit, or a faulty Powertrain Control Module (PCM).

The importance of repairing this issue lies in the fact that it affects the engine’s performance and fuel efficiency. The repair difficulty is moderate, and the repair time is estimated to be around 1.0 hour. To fix the issue, one should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2071 fault code.

Here are the symptoms to look out for:

  • The P2071 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include a decrease in engine power, rough idling, stalling, or difficulty starting the engine.
  • Additionally, the vehicle may experience poor fuel economy, reduced acceleration, or a decrease in overall performance.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The automobile fault code P2071 can be caused by a range of issues, including faulty IMTV, IMRC, and PCM.

  • The automobile fault code P2071 can be caused by a faulty Intake Manifold Tuning Valve (IMTV).
  • It can also be caused by an open or shorted IMTV harness.
  • Poor electrical connection in the IMTV circuit can also trigger this fault code.
  • Another possible cause is a faulty Intake Manifold Runner Control (IMRC).
  • Lastly, a faulty Powertrain Control Module (PCM) can also be the reason behind the P2071 fault code.

To fix the p2071 automobile fault code, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2071, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code P2071 indicates a malfunction in the intake manifold tuning valve position sensor circuit.

The diagnosis process involves checking the wiring and connections, testing the sensor, and inspecting the intake manifold. The estimated repair time for this fault code is 1.0 hour. The fixing cost will depend on the hourly rate of the auto repair shop, which typically ranges between $75 and $150 per hour.

Other factors that may affect the cost include the severity of the issue and the need for replacement parts.

The P2071 code refers to the Intake Manifold Tuning Valve (IMTV) system. The IMTV is a motorized actuated unit mounted directly to the intake manifold.

The shutter device attached to the actuator shaft controls the IMTV actuator.

The motorized IMTV unit will not be energized below approximately 2600 rpm or higher on some vehicles.

The shutter will be in the closed position not allowing airflow blend to occur in the intake manifold. The IMTV system is monitored for failure during continuous, Key ON Engine OFF (KOEO), or Key ON Engine Running (KOER) self-tests.

The test fails when the signal is more or less than an expected calibrated range.

What are the possible causes of the P2071 fault code in an automobile?

If the engine light is on and the P2071 fault code is detected, it could be due to a faulty Intake Manifold Tuning Valve (IMTV), an open or shorted IMTV harness, a poor electrical connection in the IMTV circuit, a faulty Intake Manifold Runner Control (IMRC), or a faulty Powertrain Control Module (PCM). To fix the issue, inspect the wiring harness and connectors for any damage or corrosion and check for broken or bent pins.

How can one visually inspect the wiring harness and connectors related to the P2071 fault code?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to the P2071 fault code, you may need to visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This could be caused by a faulty Intake Manifold Tuning Valve (IMTV), Intake Manifold Tuning Valve (IMTV) harness being open or shorted, Intake Manifold Tuning Valve (IMTV) circuit poor electrical connection, faulty Intake Manifold Runner Control (IMRC), or faulty Powertrain Control Module (PCM).

Is it necessary to replace the Intake Manifold Tuning Valve (IMTV) to fix the P2071 fault code, or are there other potential solutions?

The P2071 fault code can be caused by a faulty Intake Manifold Tuning Valve (IMTV), an open or shorted IMTV harness, a poor electrical connection in the IMTV circuit, a faulty Intake Manifold Runner Control (IMRC), or a faulty Powertrain Control Module (PCM). Before replacing the IMTV, it is important to visually inspect the related wiring harness and connectors for any damage or corrosion. Check for broken, bent, pushed out, or corroded connector’s pins to ensure a proper fix.
