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 V to the following sensors through the 5 Volt Reference 1 Circuit:
- Throttle Position (TP) sensor 1, 2
- Accelerator Pedal Position (APP) sensor 1
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.
