Data Validity - Invalid or Inconsistent Data from the Electronic Control Unit
The ECU is receiving inconsistent or invalid data from a sensor.
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 computer in the vehicle is getting data from a sensor that it doesn't trust because it's outside of what the computer expects.
What the computer is actually seeing
The ECU is constantly checking data inputs from various sensors and when it sees a value that doesn’t make sense, like a temperature reading that jumps from 100°F to -20°F, it throws this code.
What a healthy reading looks like
The expected data range varies by sensor, but generally for temperature sensors, values should be between 0°C to 120°C (32°F to 248°F), pressure sensors should report between 0 to 300 kPa at idle.
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.
- 1Check the sensor's wiring and connectors for damage or corrosion.
- 2Verify the voltage supply at the sensor; it should be around 5V for most electronic sensors.
- 3Test the signal coming from the sensor; ensure it falls within expected ranges. If it is outside the range, replace the sensor.
- 4Swap the suspect sensor with a known good one to see if the code clears. If not, check for issues with the ECU or ground connections.
Common causes
- Faulty sensor sending bad data
- Wiring issues creating shorts or opens
- ECU software errors
- Ground issues affecting signal integrity

Frequently asked questions
Is it safe to drive with this code?
It depends on the severity of the data issue. If it's affecting critical systems, fix it soon.
Will this code come back after repairs?
If the underlying issue is properly addressed, the code should not return.
Why does this code pair with other SPN codes?
Codes often arise from related sensor or circuit issues that affect multiple readings.
