The +C18 capacitor and +C17 capacitor circuits connect with R136 (resistor) and to ECU connector Pin D10/ELD, Electronic load detector. +C16 (capacitor) goes to +R21 (resistor), +C4 (capacitor) and to ECU connector Pin B1. That is the ECUs Ignition switched Battery voltage Power source. So what ever is on the (-) side of C16 isn't getting any power.

But c16 and c17 do not have any marking on it, actually what type capacitor is that and the value..seen it have + - i confuse either it ceramic or any else type of capacitor.

Got the tantalum cap yesterday, replace and solder back the burn component and track, also check another cap, there also burn c19, so i just change all aluminum cap. Test to start..then..... it working. Where can i find obd1 board circuit diagram, maybe some url or keyword or person sell the obd1 circuit diagram?

I have yet to find a complete one....I have only ever found circuit diagrams of an individual circuit here and there. I use an old OBD1 ECU that I carefully removed every single component. Now I have a blank circuit board and I have stuck all of the components onto a foam board. This way I can check circuits individually without any clutter.

So what do you do with your spare time? Some people, myself included, like to learn new skills in there spare time. This is an example of how I nailed my soldering technique down. Not bad when you can make $50+/hr for a hobby.

Re: P28-G01 C18 Blow..check engine light
i know this is old but iam getting code 3 CEL MAP sensor, the ecu is bad, i replace all the aluminum capacitors still the same problem, so i search on the web and find that C18 and C17 are MAP sensor related capacitors, can anyone confirm this plz

Re: P28-G01 C18 Blow..check engine light
i use my D10 to connect my wideband
for 2 years this was working great.
now sometimes my D10-ELD dont work.
anyone knows what are the capacitors on D10-ELD circuit to replace them ?

Good day I have a problem with an ecu of my civic is a p28 step the key and until you turn off the check engine light does not turn the engine probe with another ecu from a friend and caught carriage once someone knew what his ecu problem or someone happened
