Question

JUST SCANNED AN 03 ELEMENT. THE CODE IS P2646 ENHANCED DTC. WHAT IS THIS?

Accepted Answer

The code is for the vtech system. The first thing to check is the engine oil level. This code will set if the oil is low by a quart or more. If the oil is ok, then you probably need the pressure switch. Here is a Honda publication on this code.

Replace VTEC Oil Pressure

Switch for DTC P2646, P2647

NOTE: This article applies to '03-05 Accord L4s,

'03-05 Elements, and '02-05 CR-Vs.

Got a vehicle in your shop with either of these

DTCs?

  • DTC P2646 (VTEC oil pressure switch circuit

low voltage)

  • DTC P2647 (VTEC oil pressure switch circuit

high voltage)

Replacing the VTEC oil pressure switch (P/N

37250-PNE-G01, H/C XXXXXXX) usually fixes the

problem. If it doesn't, then press on with normal

troubleshooting.
