I just put a b16a into my 94 SI. I am having codes 3,6,7 come up. The car seems very sluggish but runs decent. I am using an obd-1 harness and ECU and a 98 type-r manifold and sensors. Are the TPS and Map sensors the same for OBD1 and 2. The codes say the sensors are bad but the car runs without missing or hesitation, just feels slow. Please help a brother out.

first verify all of those are hooked up properly, 2 of them are on the throttle body.

the codes are MAP, ECU and TPS.

the TPS and MAP codes could easily cause the problem you are describing.

i tried switching the map and tps since they use the same kind of plug and the car wont run. Are obd2 map and tps sensors the same as obd1

i dont *THINK* so

MOST OBDII systems are based on a different set of voltage inputs. OBDI was 0-5 volts, OBDII is .5-4.5 reason is if the ECU sees 0 volts from the TPS it knows there is a break in the wire from power to TPS or TPS to ECU, and if it sees more than 4.5 is knows there is a break on the ground side of the TPS.

but im not sure if honda did that before OBDII, some companies did.

I chanded the map sensor and it is still throwing a map code. This ECU came out of my integra and it never had any problems so i dont think the ecu is bad. Is it possible to have the car run with the map and TPS reversed

make sure you reset the ECU after each time you try to fix it.
