i have a 98 civic with a lsv turbo and im trying to hook up my af gauge and the lights dont seem to move. my power and ground is good and the purple wire is connected to the thick white wire ecu side. im trying to get this gauge working for the wideband for tuning. i get cel 41 but my o2 sensor is good?! i changed that sensor.


can someone help me out thanks!

 

Check whether 7.5A dash fuse 15 is blown.

 

Hope you dont have the HX with the seven wire o2 sensor you will have to change the engine harness, make sure you didnt accidently splice into another sensor circuit to ground because this will send a signal to the ecu for the primary 02 heater circuit failure code 41.

 

no i dont have a hx. the 02 has 4 wires.

 

im gonna go look at that thanks bro

 

upppp!!

 

alright checked fuse and its good. dont know what do im pretty much stumped!!! info guys thanks

 

Are you waiting for the sensor to warm up? It ususally takes 30 secs or so...

 

Check whether the O2 sensor plug terminal for the heater element power wire gets battery voltage with the key in ON(II).

 

yah the car was warmed up and it still would come on.

 

i need help on this one not to sure really what to do im kinda of a newb!!

 

need some help guys!!

 

You need a multimeter. Did you check whether the heater element gets voltage? Have you checked the wires for a short or open? What is the resistance of the heater element?

 

If your tuned with a turbo, you shouldnt need your O2 sensor hooked up to your ECU anyways. (depending on the tuning program)
But, since i dont know your set up, Leave the OE sensor where it is, weld in another bung for the wideband, and run the wideband sensor directly to the gauge.

 

can the 02 make the car not pass 6k?? sometimes it does sometime it dont. and idk if vtec is even opening up?!?! what cel can make the car not engage vtec?????


im noob guys sorry.
