Output Voltage Range Problem
The control module detected a voltage outside the expected range on a specific output.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The control module is noticing that the voltage it's getting back from a sensor or device is either too high or too low, which could mean a bad connection or a faulty component.
What the computer is actually seeing
The control module is monitoring an output voltage signal that should be around a specific range (0-5V). When it sees a voltage outside of this range, like above 5.5V or below 0.2V, it triggers C1615.
What a healthy reading looks like
Expected output voltage is typically between 0.5V and 4.5V for most sensors. Exact voltage can vary depending on the specific sensor.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect wiring and connectors for any visible damage or corrosion.
- 22. Check the voltage at the sensor output with a multimeter; it should read between 0.5V and 4.5V. If not, continue to the next step.
- 33. Ensure that the component connected to the output is functioning correctly; test it separately if possible.
- 44. Verify the ground connections; ensure they are clean and secure.
- 55. If all checks are good and the code is still present, consider replacing the faulty sensor or component.
Common causes
- Wiring issues such as shorts, breaks, or corrosion
- Faulty connectors or bad terminal connections
- Malfunctioning sensor or component
- Poor ground connections
