Code 1 is O2 sensor and 17 isnt a valid code, its for VSS, your VSS is cable operated, so it may be 10 and 7 which is IAT sensor and TPS sensor. All these controll fuel it my be one or combonation of all three. Start out with a new O2 and see what that does for you. Then the IAT sensor as the TPS sensors very rarely go out.

Not really going to make a difference whch one you go with, they both will do the same thing. 89' DX with a JDM B16.

No need for rep. I just know how to use our reference section, if I had a nickel for everytime Ive used the ECU code list, well Id have quite a few nickels.:D

I've had such a shit day that I didn't even think of checking there. :(

How is code 17 for vss not a valid code. if you unplug the cable from the trans you will get this code. the speedometer will no longer function and the ecu won't receive a vss pulse from the gauge cluster.
