Q: What does code P2D86 mean?

Fuel Temperature Sensor A/B Correlation. P2D86 indicates that the powertrain control module (PCM) has detected an implausible relationship between two fuel temperature sensor signals, typically Sensor A and Sensor B, which may be separate sensors or redundant elements within one assembly. The computer compares the two readings under conditions where they should closely match and sets this code when the correlation falls outside the expected range.
