Code P0698 2015 Chevrolet Silverado Description

The Engine Control Module (ECM) has four (4) internal 5 Volt reference circuits (Some models have two (2) internal 5 Volt reference circuits). Each internal reference circuit provides external 5 Volt reference circuits for more than one sensor. A short to ground or short to voltage on one external 5 Volt reference circuit can affect all the components connected to the same internal 5 Volt reference circuit. The Diagnostic Trouble Code (DTC) will be set when the ECM detects a lower than the expected voltage on any of the 5 Volt reference circuits for greater than 0.5 s.

Code Tech Notes

Disconnecting one component at a time from the affected 5 Volt reference circuit while observing the scan tool 5 Volt Reference Circuit Status parameter may help locate the fault. The scan tool parameter will change from Malfunction to OK when the source of the fault is disconnected. If all 5 Volt reference components have been disconnected and a fault is still indicated, the fault may exist in the wiring harness.

The 5 Volt reference 3 circuit provides 5 Volt to the following sensors: (Some models may have different sensors, please consult the factory service manual for the list of sensors for your model and year)

- Accelerator pedal position sensor 2
- Manifold absolute pressure sensor

1. What does the OBDII code P0698 mean on a 2015 Chevrolet Silverado?

P0698 indicates a "5V Reference 3 Circuit Low Voltage," meaning the vehicle's ECM has detected a low voltage issue in the 5-volt reference circuit that supplies certain sensors.

2. What are the common symptoms of code P0698 in a 2015 Chevrolet Silverado?

Symptoms may include a check engine light, poor engine performance, issues with transmission shifting, stalling, or failure of specific sensors to function properly.

3. What causes the P0698 code to appear on a 2015 Chevrolet Silverado?

Common causes include a short to ground in the 5V reference circuit, a faulty sensor connected to the circuit, damaged wiring or connectors, or a malfunctioning ECM.

4. Which sensors could be affected by the P0698 code on a 2015 Chevrolet Silverado?

The code typically affects sensors relying on the 5V reference, such as the throttle position sensor (TPS), manifold absolute pressure (MAP) sensor, or other engine management sensors.

5. Can I continue driving my 2015 Chevrolet Silverado with the P0698 code?

It is not recommended to drive for extended periods with this code, as it can cause drivability issues and potentially lead to further damage if not addressed.

6. How can I diagnose the P0698 code on my Chevrolet Silverado?

Start by inspecting the wiring and connectors for damage or corrosion, test the sensors on the 5V reference circuit, and use a multimeter to check voltage at the ECM and sensors.
