Code P0698 2017 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

What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the P0698 2017 Chevrolet Silverado code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P0698 2017 Chevrolet Silverado Code

1. What does OBDII code P0698 mean on a 2017 Chevrolet Silverado?

P0698 indicates a "5V Reference 3 Circuit Low Voltage," meaning the vehicle's control module has detected an issue with the 5-volt reference signal in one of its circuits.

2. What are the common symptoms of code P0698 in a 2017 Chevrolet Silverado?

Symptoms may include the check engine light turning on, poor engine performance, issues with sensors like the throttle position sensor, and erratic transmission shifting.

3. What causes the P0698 code to appear?

Common causes include a faulty sensor (like the throttle position or pressure sensor), damaged wiring or connectors in the 5V reference circuit, or a malfunctioning powertrain control module (PCM).

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

Start by checking the wiring and connectors for damage or corrosion in the 5V reference circuit. Use a multimeter to verify voltage and continuity, and test any related sensors.

5. What sensors are typically associated with the 5V reference 3 circuit on a 2017 Chevrolet Silverado?

Sensors such as the throttle position sensor, fuel pressure sensor, or transmission pressure sensor may be linked to the 5V reference 3 circuit.

6. Can I drive my 2017 Silverado with the P0698 code?

It's not recommended, as the underlying issue could affect engine performance, fuel efficiency, or transmission operation, potentially leading to further damage.

7. How do I fix the P0698 code on my Silverado?

Repairs may involve replacing a damaged sensor, repairing or replacing faulty wiring, cleaning corroded connectors, or, in rare cases, reprogramming or replacing the PCM.

8. Is P0698 a common code for the 2017 Chevrolet Silverado?

While not extremely common, it can occur in vehicles where sensors or wiring in the 5V reference circuit are prone to damage or wear.

9. How much does it cost to repair a P0698 code?

Repair costs vary depending on the root cause. Fixing a damaged wire or connector may cost under $100, while sensor replacement could range from $150 to $300. PCM repairs can exceed $500.

10. Can a bad PCM cause the P0698 code?

Yes, although rare, a malfunctioning PCM can fail to supply the correct 5V reference signal, triggering the P0698 code.
