P2019 - OBD Trouble Code
OBD Code P2019 - Intake Manifold Runner Position Sensor/Switch Circuit Bank 2
The
trouble code P2019 can be explicated as Intake Manifold Runner Position
Sensor/Switch Circuit Bank 2. If the engine control module would detect a
variation in the voltage coming from the intake manifold runner position sensor
delivered performance that is outside the parameters set by the automobile
manufacturer, then it would store the P2019 fault code. This would give rise to
the flashing up of the check engine light.

This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.
What causes this problem with the Intake Manifold Runner Position Sensor/Switch Circuit Bank 2?
- The wiring harness is not shut or tiny
- There might be poor electrical connection
- Intake manifold runner control solenoid might be flawed
- Some issues related to the intake manifold runner flaps
- Unusable Intake runner position sensor bank 2
Replace/Repair These Parts To Fix Code P2019
- Engine Control
Module - Want to know the most common reason behind the
failure in the engine control module? Corrosion or damage because of moisture
can cause ECM failure. Corrosion might enter the ECM through the wiring harness
and moisture can enter by a failure in the seals in the ECM itself.
- Powertrain Control
Module - The PCM makes the engine and transmission work
in tandem. Any issue with the powertrain control module will cause major
problems with the efficient running of the vehicle.
- Intake Manifold
- The primary function of the intake manifold is to evenly distribute
the combustion mixture (or just air in a direct injection engine) to each
intake port in the cylinder head(s). Even distribution is important to optimize
the efficiency and performance of the engine. Thus, replace it now!
- Electronic Control
Unit - If your vehicle fails to start for no apparent
reason, this is also a good indicator that there can be some issues with the
ECU. If you check the car battery, starter and other common electrical
components, and the vehicle still does not start, a quirky electronic control
unit should be the next logical thing to consider.
- Throttle Position
Sensor - If the TPS isn’t providing the right input, the
onboard computer cannot direct the engine to work properly. When the car
accelerates while driving, it usually means the butterfly valve inside the
throttle has closed up and pops open suddenly when the driver presses on the
accelerator. This gives the car an unintended burst of speed that occurs
because the sensor cannot detect the closed position of the throttle. Replace
faulty TPS now!

car problems pointed out easily. Our diagnostic tools collection will come
handy to do so and resolve all your vehicle problems. Visit today!

Easy Diagnosis Of Engine Error OBD Code P2019
Here are some steps which you should follow in order to diagnose this fault code:
- You must always start with a technical service bulletin search for your particular vehicle.
- Advanced diagnostic steps become very vehicle specific and may require the appropriate advanced equipment and knowledge to perform accurately.
- We include basic steps below but refer to a vehicle year/make/model/powertrain specific repair guide for specific steps for your vehicle.
- The diagnosis should be started by the visual inspection of system wiring as well as connector. An open circuit can be caused due to corrosion in the IMRC actuator connectors, so it is essential to pay attention to these.
- A scanner should be used by a professional technician to notice the freeze frame data, to assemble details about the code.
- The mechanic can also check to see if there is presence of additional trouble codes. Now if there are a number of codes, then they should be addressed in the same order in which they are appearing on the scanner.
- After that the mechanic should reset the trouble codes, restart the vehicle, and check to see if the code remains detected.
- If it does not, then the code was likely triggered incorrectly, or represents an intermittent issue. Now once the code is reset, access should be gained for IMRC actuator solenoid and IMRC runner position sensor.
- One can always consult a vehicle information source for checking recommendations for these constituents. A DVOM should be used to perform a resistance test on both constituents.
- If the actuator or the position sensor are not as per the specifications set by the manufacturer, then the faulty parts should be replaced and then retest the entire system once again.
- If the actuator resistance and sensor resistance are both as per the specifications set by the manufacturer, then a DVOM should be used to check the resistance and continuity on all system circuits.
- You can always avoid the controller damage; this can be done by disconnecting all related controllers before testing.
- Repair or restore the shorted or open circuits as per the requirements. Check the IMR flap binding with the actuator disconnected from the shaft.
Common Mistakes When Diagnosing The P2019 Code
- The most common mistake while diagnosing this code is missing out on diagnosing steps which further leads to the expensive and unnecessary replacements. It is always recommended to seek help of experienced diagnostician to avoid any mistakes.
- The mechanic should always look for basic causes like the vacuum line that is leaking before moving on to more expensive and complex intake manifold runner control solenoid.
