Redundant Sensor Data Inconsistency
The data from multiple sensors does not match and indicates a potential failure.
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 comparing readings from two sensors that should show similar values but they don't match, which might mean one of the sensors is faulty or has a bad connection.
What the computer is actually seeing
The ECM sees two sensors providing different values for the same parameter. For example, if one sensor reads 78°F and the other reads 90°F, it triggers this code.
What a healthy reading looks like
Both sensors should read within 5% of each other under normal operating conditions. If one sensor reads significantly outside 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. Inspect the wiring and connectors for damage or corrosion between the sensors. Repair any issues found. Decision: If repaired, clear the code and test drive. If code returns, continue to step 2.
- 22. Check the sensor outputs with a scan tool or multimeter. Compare the values of the two sensors under similar conditions. Decision: If values are within expected range, look for other fault causes. If out of range, go to step 3.
- 33. Swap the suspect sensor with a known good sensor and clear the code. Decision: If the code returns, the original sensor was likely fine; check wiring and connections. If the code does not return, replace the faulty sensor.
Common causes
- Faulty sensor
- Wiring issue between sensors
- Bad connector or corrosion
- Software glitch in the ECM

Frequently asked questions
Is it safe to drive with this code active?
It's generally safe but monitor performance closely; address the issue soon to prevent further damage.
Will the code come back after clearing it?
If the problem isn't fixed, yes, the code will likely reappear.
Why does this code pair with SPN 2336?
Both codes relate to sensor data consistency issues and often stem from similar wiring or sensor problems.
