as in the jumper to jump to cause the check engine light to flash codes.
theres a 2 pin plug that isnt plugged into anything near the passenger kick panel. jump that and turn the key into the on position, don't start the car. and count the flashes in morse code style remember to include pauses.
sorry i cannot find a pic of one on hondaswap now The new cel thread (how-to & codes) - Honda-Tech
roughly that area theres a 2 pin one and a 3 pin over there if i remember correctly use the 2 pin, jump it with a metal paperclip, or loose copper wire if need be.
to reset the CEL light pull your hazard fuse for 10 seconds
ok so i did the jumper and got 8 codes i have a m/t and i got code (5,6,9,14,19,21,22,and 41) any suggestions my set up is D16z6 block, D15b2 tranny, D16a6 intake mani with OBD0 harness with ebay OBD1 conversion harness witch comes with dizzy adaptor, vtec wiring, 02 sensor, and ecu conversion harness running a P28 the (first code 5 is the MAP sensor it is the map off of a D16z6 throttlebody so not sure why that code is up),( the 2nd code 6 is engine collant temp i noticed to coolant temp sensors on the engine but i have only the one in from hooked up becuase not sure where to wire connection is for the one in the back am "i supposed to splice into the one in from and run it to the back?") the( 3rd code 9 NO.1 cylinder position sensor "where the hell is that") the (4th code 14 iac valve will the one on the OBD0 intake work with the OBD1 ecu and engine?) ( 5th code 19 A/T lock up control solenoid "i have a M/T what the hell") (6th code 21 VTec control solenoid) (7th code 22 VTec pressure solenoid) and (8th code 41 heated oxygen sensor heater "WHATS THAT?"
this page has some useful information. If it is an automatic you can convert it to manual.
If it is a manual and still has the code, reset the ecu again and double check the code. If it still has it, I honestly don't know for sure, double check the ecu in another car, as well as your other ecu.
