code 7 w/ h22 swap into 4th gen accord
Hey guys,
I just finished swapping a 95 JDM H22a into my 93 accord lx. Everything is wired up correctly I believe. The car cranks, and surges to about 1500-2k rpm as do most cold honda engines. As soon as it gets up to idle level, it dies and I get a code 7 for TPS sensor. I checked the voltage across the connector as the service manual said, and its dead on. I dont have the equipment to check the voltage across the ECU. So would this mean I need a new TPS sensor?? The one I am currently using is from my friends b18. This would still work right? I assumed that all TPS sensors were the same? Somebody please help me out as I believe this is my last hurdle. Thanx!!!

You need to check your voltages at the ecu. First do a continuity test from the tps sensor connector to each of your ecu pins (d11 - red/black - Alternating signal, d22 - green/white - Ground, and d20 - yellow/white - ecu signal).
Yes ALL 4 cylinder honda motor tps sensors are the same. When you say you checked the voltage across the connector are you saying you checked from the green/white wire to the yellow/white wire and you measured 5 volts? If so, thats just ECU signal. Its not the alternating voltage you need to be looking for.
In order to accurately check for your .5 volts at closed throttle and your 4.5 volts at WOT you need to measure across the red/black wire and the green/white wire. IF you can find a way to tap into the wire at the sensor then do it there. If not, you HAVE to do it at the ECU.
I can pretty much lay money on what you did wrong though. You more then likely (just like i did) just put the new TPS straight on and tried adjusting it that way. You CANNOT do it like this. You have to actually take the sensor and turn it about 90 degrees down. Basically, line the TPS up like you are going to just put it straight on, then turn it down, far enough to where the connector connection is just about pointing down and to the right. The TPS will then go on and you can then turn it back up and to the left and you should then be able to get your .5 and your 4.5.
The afformentioned directions (down and right, up and left) were made as if you were standing in front of the motor. If you've been messin with this problem for awhile, im sure you know what im talking about.
HTH!

Re: (projekakkord)
Ok. You may need to re adjust your idle screw (i had to when i put my new TPS on). Also, make sure your IACV is connected (i disconnected mine for something else and forgot to reconnect it and it did the same thing).
Also, recheck your codes again. Just to be sure that nothing else is broken.
