Invalid Data Received from Electronic Control Unit (ECU)
The ECU is reporting invalid or corrupted data to the system.
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 engine's computer is getting bad information from one of its sensors, making it think something's wrong when it might not be.
What the computer is actually seeing
The ECU detects values outside normal operating conditions, such as erratic voltage levels or data packets that don't match expectations, potentially from sensors or communication lines.
What a healthy reading looks like
General voltage levels should range from 0.5 to 4.5 volts for analog sensors; CAN bus messages should be within established protocol rates (usually 250 Kbps).
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. Check for any visible damage to the wiring and connectors related to the ECU and sensors. Clear the code and see if it returns.
- 22. Inspect the sensor data using a scan tool; look for erratic readings indicating bad sensors (e.g., a temperature sensor reading -40°F or +300°F when it should be between 32°F and 220°F). If erratic readings exist, replace the sensor.
- 33. Perform an integrity check on the CAN network; use a multimeter to verify voltage levels are consistent with expected values. If inconsistent, address wiring issues or replace the affected component.
Common causes
- Corrupted data from a sensor
- Faulty or damaged wiring
- Poor connections or shorts in the CAN network
Typical repair cost

Frequently asked questions
Can I drive my vehicle with this code?
It's not safe to drive if the ECU is giving invalid signals, as it might lead to unexpected engine performance issues.
Will this code come back after repairs?
If the root cause is fixed, the code shouldn't return; however, intermittent wiring issues might need further investigation.
Why is this code showing along with another code?
Multiple codes can indicate a shared root cause, such as a wiring issue affecting all related sensors.
