Data Erroneous or Inconsistent with Input Data from Other Sources
There is a conflict in data received from sensors or the control 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)
The computer is getting different information from different sensors that don't match, leading to confusion about vehicle performance.
What the computer is actually seeing
The engine or transmission control module (ECM/TCM) observes discrepancies between input data from various sensors, such as pressure or temperature readings, affecting how it adjusts engine or transmission behavior.
What a healthy reading looks like
For example, if the temperature sensor reads 200°F but the coolant level is low, the ECM may flag a conflict since coolant cannot be at normal temp with low levels.
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 wiring and connectors for damage or corrosion. Look for obvious shorts or breaks.
- 22. Verify sensor operation by checking input/output values with a scan tool during various operating conditions.
- 33. Compare readings from conflicting sensors. For example, does the pressure sensor match what the gauge reads? It should conform ±5% under normal conditions.
- 44. Inspect for fluid leaks or system blockages causing incorrect readings; fix any leaks found.
- 55. If no faults are found, test the control module for errors or recalibrate if necessary.
Common causes
- Faulty sensor sending inconsistent data
- Wiring issues causing erroneous signals
- Faulty control module misprocessing the data

Frequently asked questions
Is it safe to drive with this code?
It's moderate severity and may cause drivability issues, so it's best to fix this soon.
Will this code come back after clearing it?
If the underlying issue isn't fixed, it likely will return.
Why does this code pair with others?
It's common for systems to have interrelated sensors, and problems can emerge that affect multiple readings.
