EG-Z6-Sedan

Im having some troubles with my z6 swap into my 93 civic sedan. Im throwing codes 3,7,21,41. I have the ex/si engine harness on the z6. Whenever i plug the engine harness's map sensor plug in the car starts to "idle jump" from 1000-1500. Im curently working on wiring up the vtec to the ecu as the car isnt prewired. My question is once thats wired up will it clear out my other codes or will more wiring need to be done?

If you used an EX/Si engine harness you wont have a working MAP plug if you're using the one in the engine harness.

'92 - '93 Civics factory equipped with a D15B7 have a firewall mounted MAP sensor bolted to the fuel filter bracket. Unplug this as it's not doing anything and plug the connector into the MAP sensor on the throttle body.

As far as you TPS code, I'd say you have the TPS connector plugged into the MAP sensor.

Code 21 will go away when you add the vtec wiring.

Code 41 is for a heated oxygen sensor, either it's not wired correctly (unlikely since none of the wiring changes when doing that swap, unless your new harness was hacked up) or the sensor is bad (pretty common, especially if the sensor was dropped, bumped or removed from the manifold and reinstalled)

Alright man ill gi e this a try. Should i be using the tps sensor from the ex harness for the tps or the map plug. Other question does the ex/si map plug become a dead plug in this swap?

TPS goes to TPS

It does, just let it hang.
