P2019 Code: Intake Manifold Position Sensor Circuit (Bank 2)

The ECU lost contact with the second half of your engine. P2019 affects Bank 2 specifically. Here is how to verify if the sensor is truly dead.

1. What Does P2019 Mean?

The code P2019 stands for "Intake Manifold Runner Position Sensor/Switch Circuit Bank 2."

If you have a V6, V8, or V10 engine, you likely have two separate intake manifolds (or a split manifold). Each side has its own flap system.

The ECU sends a command to move the flaps.
It expects the Position Sensor on Bank 2 to report back the new angle.
P2019 means the signal from Bank 2 is missing, erratic, or out of spec. The ECU is "blind" on that side.

3. Why Did the Bank 2 Sensor Fail?

The causes for P2019 are identical to Bank 1, but the location is different.

Wiring Damage (Rear Bank): On transverse V6 engines (like in Minivans or SUVs), Bank 1 is usually against the firewall (hard to reach), and Bank 2 is near the radiator. However, sometimes heat from the exhaust manifold cooks the wiring insulation on the Bank 2 sensor.
Sensor Wear: The potentiometer tracks inside the sensor wear down over thousands of cycles, creating dead spots.
Connector Corrosion: Check if coolant or oil has leaked onto the Bank 2 sensor plug.

4. Diagnosis: The "Comparison Test"

The beauty of having two banks is that you have a built-in reference. If Bank 1 is working, you can compare its data to Bank 2 using the iCarsoft CR Ultra P.

Step-by-Step:

Connect Scanner: Go to Live Data in the ECU menu.
Select Streams: Select both:
- Intake Manifold Runner Position Bank 1
- Intake Manifold Runner Position Bank 2
Rev the Engine: Snap the throttle safely.
- Normal: Both values should rise and fall together (e.g., both hit 90% then drop to 10%).
- Faulty: If Bank 1 moves, but Bank 2 stays flat (0V or 0%), you have confirmed the Bank 2 sensor circuit is dead.

Graph Both Banks Simultaneously

You can't do a comparison test with a basic code reader. The iCarsoft CR MAX BT lets you graph multiple data streams side-by-side to instantly spot the dead sensor.

6. Frequently Asked Questions

Q: Is Bank 2 the Driver or Passenger side?
A: It depends on the car. For Ford/Lincoln, Bank 2 is usually the Driver side. For Chevy/GM, it's usually the Passenger side. Always look up the firing order diagram for your specific VIN.

Q: What happens if I ignore P2019?
A: The ECU will likely disable the intake runners on both banks to keep the engine balanced. You will lose power, burn more gas, and potentially fail emissions tests.

Q: Is there a specific "Low" or "High" code for Bank 2?
A: Yes.
• P2021: Circuit Low (Short to Ground) Bank 2.
• P2022: Circuit High (Open/Short to Power) Bank 2.
