Invalid Data Received From ECU
The ECU detected corrupt or invalid data from another module.
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)
Your vehicle's engine control unit (ECU) is getting bad data from another part of the system, which can affect performance.
What the computer is actually seeing
The ECU expects to receive valid signals for parameters like voltage or sensor readings but is seeing values that are outside the expected range or inconsistent with previous readings.
What a healthy reading looks like
Voltage signals should typically fall between 0.2V and 4.9V for most sensors, and if they stray from this range, it indicates a fault.
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 related DTCs. If multiple codes are present, focus on the one that may indicate which module is failing.
- 22. Inspect wiring and connectors associated with the affected modules. Look for frays, corrosion, or loose connections.
- 33. Verify signal integrity with a multimeter. Ensure voltage levels match expected values (0.2V to 4.9V) under varying engine conditions.
- 44. Check for updates or re-flash the ECU if you suspect a software issue.
- 55. Swap suspect sensors or modules with known good ones to see if the issue persists.
Common causes
- Faulty sensor
- Poor wiring connections
- Corrupted ECU software
- Intermittent electrical issues

Frequently asked questions
Is it safe to drive with this code?
It's moderate severity, so you can drive but address it soon to avoid performance issues.
Will this issue come back after I fix it?
If caused by an intermittent fault, it may. Ensure thorough checks on electrical connections.
Why does this code often pair with other codes?
Multiple codes indicate the same issue or related system faults, requiring a clustered diagnostic approach.
