I've got a B20z in my 99 Dx, and I'm running a p75 (LS OBD2) 5 speed ecu.
I'm getting codes 7 and 65...at least its starting, though!

EDIT: I did a searches on HYBRID, and found the following info:

Code 7 is a TP Sensor (Throttle Position) (defective circuit or unplugged / defective sensor).

Code 65 is an Oxygen Sensor Heater (Secondary) (malfunctioning or defective oxygen sensor heater).

But where do I go from here?

Thanks again.

I have taken the beast around the neighborhood a few times, and found some things I didnt notice before....

My tach no longer works...it's a stock Si guage cluster.

My fuel pump doesn't just prime when the key is turned to the "on" position, it stays running.

It's 4 am...I'm scared of what else I'm going to find in the morning.

 

Hmmm. Was the TPS sensor cracked/smashed/broken when you installed the motor? Sometimes when dropping in the motor, it'll bang on the firewall and crack. Just be very careful when lowering the motor in.

Secondly, did you hook up both O2 sensors?

 

I checked it out, and it doesnt look to be damaged...maybe it's an internal problem. How can I make sure?

Yes, they're both hooked up.

I fixed the exhaust leak between the exhaust manifold and the a-pipe. Someone said that might have been the reason why that code was thrown.

 

Code 65 could also be a short/open circuit on your SHO2S. My ecu is throwin that exact same code. But the reason for mine is a open circuit. You should do a continuity check on the sensor wires with an ohmmeter before you replace the sensors. Any Honda/Acura dealer can give you a printout of which wires you need to check. Just pray the Service Manager isn't a dick cuz he might not want to make copies, but he should at least let you look at the manual and write down the info you need. Good luck with your hybrid.

 

Thanks for the info and tips, guys.

I'm going to re-check the wiring to see if it was done correcly. I'm positive thats where my problems are.
