Circuit Description
WARNING: This page is about a different car, the 2006 Suzuki Reno and 2006 Suzuki Forenza. However, it is still accessible from the selected car via links, so may be relevant.
The Engine Control Module (ECM) provides 5 volts to the following sensors through the 5 Volt Reference 2 Circuit:
- Manifold Absolute Pressure (MAP) sensor
- Exhaust Gas Recirculation position sensor
- Accelerator Pedal Position (APP) sensor
- A/C Pressure (ACP) sensor
- Rough Road sensor
- Fuel Tank Pressure (FTP) sensor
A circuit condition on one sensor 5 volt reference circuit may affect the other sensor 5 volt reference circuits. The ECM monitors the voltage on the 5 volt reference circuit. If the ECM detects that the voltage is out of tolerance, a DTC sets.
