d15b?

[isa1023]

I'm driving my second JDM D15B-powered ESi for a month now and the CEL persists throughout drives, from start to engine off, and which is probably due to a failing sensor (maybe the throttle position sensor).

Wala naman naging problema except that on cold starts, the ECU won't do the Honda-normal 1500 rpm cold idle speed til thermostat opens.

Regarding your question, yours is probably running on a D15B block (as seen in the picture) but not on a JDM D15B VTEC head, as you would like to believe.

Not all D15s are D15Bs.

Taking a second look at your engine, it's probably JDM D15B block running on local City Type Z or Civic LXi head. These heads are interchangeable bolt-ons to D15s.

we have the same engine TS, but yung saken is may 2 vtec solenoids, d15b 3 stage vtec, bat ganun wala ka solenoid, possible din na pinalitan yung block niya before nang d15b block and iba ang head kaya non vtec, nilagay lang yung valve cover nang d15b, wala kasi talaga vtec na nakalagay sa d15b 3 stage valve cover..

Yes, pero wala siyang solenoid eh.

Yung silvertop head na yun is yung pang-3 stage diba?
