What Does P2017 Mean?
DTC P2017 indicates the intake manifold runner position sensor on bank 1 is reporting a signal voltage above the maximum threshold expected by the ECM. This high-voltage condition typically points to an open signal return (ground) circuit, a short to the reference voltage line, or a failed sensor with high output. The ECM cannot determine runner position accurately.
Common Causes
30%
Open ground (signal return) wire from the IMRC position sensor to ECM
25%
Short between the sensor signal wire and the 5V reference wire
25%
Failed IMRC position sensor with high fixed output
15%
Corroded connector with high-resistance ground contact
5%
ECM analog input pull-up fault
Diagnostic Steps
1
Measure voltage at the IMRC position sensor signal pin with key on; a reading near 5V suggests an open ground or signal-to-reference short.
2
Check the sensor ground (signal return) circuit for continuity from the sensor connector back to the ECM ground pin.
3
Inspect for cross-contamination between the signal and reference voltage wires in the harness or connector.
4
Disconnect the sensor and measure signal wire voltage at the harness side; if it drops to near 0V, the sensor itself is the fault.
5
If wiring and sensor check good, test the ECM input pin with a known-good simulated signal.

The most common cause of P2017 (Intake Manifold Runner Position Sensor/Switch Circuit High Bank 1) is: Open ground (signal return) wire from the IMRC position sensor to ECM
Typical repair costs for P2017 range from $70 to $350, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Low safety concern. Position feedback is lost for bank 1 IMRC but the engine will continue to run with a fixed runner configuration. Vehicle is safe to drive.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2017 to identify the root cause.
