I took my recently purchased 96 DX with a B16A2 swap to AutoZone in order see why the CEL was on. I didn't expect to get 7 different codes. Ill list them here

P0453: FTP sensor circuit high voltage
P1337: CSF senson no signal
P0135: A/F sensor 1 heater system malfunction
P0113: IAT sensor circuit high voltage
P0122: TP sensor "A" circuit low voltage
P0141: Secondary H02S12 (Heated oxygen sensor - Bank 1 Sensor 2) circuit heater malfunction

I also took a couple pics of random wire that aren't plugged into anything. Im wondering if any of the unplugged wires in the pics could cause any of these codes.

 

First one looks like your IAT sensor is nada. Probably because there was nowhere to mount it in that ridiculously short intake pipe. Drill a hole for the grommet and sensor.

The other ones might be A/C.

 

the other ones are for the a/c condenser fan and evaporator and sub harness that has another harness that goes to the compressor

 

I see the CSF sensor and it is unplugged however I have no idea where or what to plug it into. Anyone know what wire its supposed to connect to?

 

If memory serves, the csf sensor plugs into the oil pump. Someone correct me if I'm wrong on this.

This is also worth mentioning. If you have a JDM engine, they didn't have a csf sensor but an non JDM ECU will look for one. Not sure I this is case with you or not.

 

I see the sensor coming out of the oil pump but I don't see a plug nearby to plug it into
