ok guys here my problem...i have a 91 civic si with a DOHC ZC engine...it ran fine till swaped the tranny ....weird huh

just swaped the blown L3 for another L3

<U>symptoms-</U>
- started the car and it idles @ 1200rpm
- wont rev past 3100rpm
- i got a code 9 (No. 1 Cyl Pos)
- running rich the spark plugs are fueled up

<U>what i have done-</U>
- checked wires comming from the dizzy plug to the Cyl pos senser (DOHC ZC have it on the exhaust cam)
-had spare sensor and swaped it out (still ran like the same, i did reset the ECU 10amp HAZARD fuse)
-i did check the cam timming and thats dead nuts.

did i forget a ground somewhere?
where else can i look where dose it get its ground side on the circuit...threw the ecu everything went well except this.....


WHAT WILL CAUSE LIMP MODE.......??????

 

why are you asking what would cause limp mode??? a code nine will definitly cause limp mode. all i can say is that the sensor is messed up.. but check the conection at the ecu. i dont think that would be the problem because you didnt have to mess with the pins but it could be it.

 

Did you hook up the tranny ground after reinstalling? Code 9 is a timing issue (or like previously said could be the sensor itself), is your dizzy wired up correctly? How did you set the cam timing? It can be a pain in the *** on the DOHC ZC sometimes. What was this "spare sensor" that you swapped out?

 

i was told that a code 9 wont cause limp mode

yes , code 9 on a dohc ZC is the no.1 cly pos sensor with is on the exhast cam...seprae from the dizzy...it ran fine before i did the tranny swap

how do u set timming on a DOHC ZC

 

Eiether a crank angle sensor, or a faulty ecu.

 

is the Crank angle in the dizzy

 

on a DOHC ZC will a code 9 mean that the no.1 pos sesor on the exhast cam be bad...i have swaped it from a diffrent one still the same.... where does this circuit ground to??? ..... tomaroow ill get the muiltmeter and the osciloscope out and test the dizzy....any other ideads

 

when i put my new tranny in i got a code 1 and 7. i pinched the wires in the tranny housing. check that if u pinched any wires.

 

FIXED!!!!!!!!!!!!!!!
the old harness were to blame and frade wires re sodered them and all set
plus i got a code 14 (iACV)
the iacv pins were slighty pulled form there clip...code nine was gone ....but a code 14 came up ....replaced iacv...same idel serge....got some throttle body cleaner out and sprayed all vacume lines
nothing well the throttle body gasket was blown .....note to self throttle body gasket can case symtoms for a bad iacv
