Whats up guys, I recently swapped a obd1 GSR in my obd2a Ek. Using an ex harness and wiring everything properly. Using a obd2a GSR ecu.

It's now throwing codes for iat and tps. I know for a fact wiring was done correctly. I'm 90% sure that the iat sensor is faulty, does Honda iat sensors vary between models?

Now with the tps I replaced it with my buddies tps off of his obd1 b16, it's still throwing a code, when we tried to set the tps (.5v closed 4.5v wot) we noticed 2 wires with 5v, but through research found out we are supposed togo off the middle wire. Our problem is itself can't get a signal for more than a sec making it impossible to set. Im beyond stumped on this so any help would be extremely appreciated.

Thanks.

 

The wire from the ecu is probably the problem you need to take ecu out ...get a wiring diagram for your stock car for the inside harness...and a wiring diagram for an integral...or search online. Sounds like it's not the tps...it's the wire. Should have a power ...ground...and a sensor wire on the tps. Back tract from there on wiring diagram.

 

Have you ran into the problem of the B18c headers and the ek exhaust hook up?

 

Got to cut it a bit
