can't say I've ever seen this code.
P1611-SUPERCHARGER BYPASS VALVE POSITION SENSOR 1 CIRCUIT HIGH
Theory of Operation
The Supercharger boost pressure is managed by the use of a Supercharger Bypass (SCB) Valve. The PCM can vary the position of the SCB Valve to control the amount of boost. The SCB system uses two Position Sensors to monitor the SCB blade position. Position Sensors are located within the SCB Valve assembly. Each sensor has its own Signal circuit. Both sensors share a 5-Volt reference circuit (Supply) and a low reference circuit (Sensor Return). The Powertrain Control Module (PCM) monitors the SCB Valve Sensor data. Each Signal circuit provides the PCM with a signal voltage proportional to SCB blade movement. The PCM monitors the data to verify that the indicated SCB position is correct.
When Monitored and Set Conditions
This diagnostic runs continuously when the following conditions are met:
- With the ignition on.
- Battery voltage greater than 10.4 volts.
- The TPS 1 Signal voltage is above the maximum calibrated threshold.
- The MIL light will illuminate.
