Thinking of buying a 93 eg w/ a LS/Vetec swap, LS block from a 94 integra gsr and head from a 2000 Si. Only problem with it is the vetec is not activating. Was told he doesn't know why but it may need a knock sensor? hatch still pulls hard but just imagine the vetec activating. All so needs oxygen sensor. Need advice thanks.

 

Check what ECU is the car using, if she's running on a p28 there's no need for the knock sensor since that ECU doesn't use knock sensor. Check the vtec wiring, is it activating through a RPM Activated Switch, or a toggle switch? Or is it wired up to the ECU OEM style? My advice, borrow a chiped P28 from a friend and go plug it in on the hatch, check if the vtec works!

Let me know! L8R

heeeeee

 

check oil level, if it is low, VTEC will not work. if it was a knock sensor causing the problem, you would be getting a check engine light. if you are not getting a CEL, then make sure the bulb is there. easiest way is to turn the key to accessory position and the light should light up under all circumstances. if it doesn't, the bulb is either bad or taken out.

 

" LS block from a 94 integra gsr " so is it a ls or a gsr?

 

The CEL is on, any other advice

 

the CEL is on while the car is running, or when the key is turned to accessory?

 

When the car is running.

 

check your IM (instant messenger on here, not intake manifold)

 

How do you do that ?

 

Vetec Eh?

you have to find out which code is in the computer to get better help.

vtec wont engage without a knock sensor unless you have a chipped ecu

 

wow VETEC... check which code its throwing.. it may be the VTEC ( ) selelnoid. It could also be because hes using an obd2 ecu that doesnt see a knock sensor???

its vtec.

first step is to find out why your CEL is on.

here is a vtec troubleshoot.
