i have a 91 hatch that has a 99 gsr in it with a obd1 p72 that is chipped not sure what chip is in it but i have a cel for speed sensor and need to know if there is anyway of getting rid of this cel. it has a 90-91 si cluster. can anyone help?

thanks!

 

Is speedo working? If not may need to fix either speed sensor or cable. Have you tried a different ecu to see if code still appears? I think you have to wire a certain wire to blue wire on dizzy I will check tomorrow for you to tell you what color it is

 

Yeah you need to run a wire from the ecu to the blue wire behind the cluster. I cannot remember the correct wire out of the ecu though.

 

Mines is at the dizzy but behind cluster will work just as well

 

Hey I found this online look at it it is pin (b10) vss that you will have to extend to either dizzy or cluster (blue wire) http://technet.ff-squad.com/wiring.obd1.htm
Hope that helps. Oh forgot to mention to not cut wire but add an additional wire to that on on your jumper harness.

 

thanks a lot appreciate it! im also coding for crank sensor it has the MSD blaster ss cap and the coil is takin out of the dizzy would that cause it to code for crank sensor or do i just need to get a new dizzy? the car has been jumped from obo to obd1

 

i just got this car the other day so and i dont know if its the wiring or not if it was wired from the ecu end wrong could that cause it? if anyone has any links to a page to help me out i would appreciate it a lot

 

Yea prolly would throw a crank code cuz of the msd but will double check on that once you get the first code dealt with un plug battery for a while to erase codes from ecu and recheck them to see wat you got left.

 

Took the cat for a drive today its coding for o2 sensor, tps, vtec spool, and still for crank sensor

 

If not already installed you need a four wire o2, also check your tps with a voltmeter, with vtec spool see if the vtec gasket is clogged and clean it or get new gasket from Honda, as the crank sensor has to deal with dizzy. Also are you running a obd1 dizzy?

 

the o2 sensor isnt even install in the car there is no spot in the exhuast for it so i will have to take it in and have a bung installed as far as location for the o2 sensor it has a obd1 jumper does it need to go in before the car or after that cat? it has an obd1 dizzy how to do you check the tps with a volt meter? thanks for all the help

 

There are stickys on this site for checking tps use the search bar up top, as for o2 they usually go before the cat hopefully this helps because idk which harness you are using
