Important Caveats
- • Counterfeit Hondata KPro units are common and mimic wiring faults; verify the ECU is genuine.
- • A failed internal 5 V reference/voltage regulator on the ECU can throw P0117 (ECT low voltage) and P0112 (IAT low voltage) even in a known-good car, so confirm the ECU is healthy before blaming the swap harness.
- • EUDM engine harness on a USDM ECU requires re-pinning; the connectors mating physically does not mean the pins align.
- • The O2 heater circuit is electrical and independent of coolant temperature; only VTEC engagement depends on ECT.
