The connection might not be sound - did you use the supplied wire crimp to attach it to the stock wire and connector?

how can i check the connection????

thanx man

 

does it lose signal exactly at 15 mins each time your start the car?

Check the connection by placing a volt meter on it and measuring current. See if the Current matchs what the PFC displays

 

no i drove it after instal for 15 min aND voltage just dropped

when i check it at home returning from the drive

do u have a pfc wish???

what does ur say????

mike

 

its runs alot better tho

 

When warm, the voltage at the stock 02 sensor should be around .7-.9 volts. It will vary with temps/ cars/ and richness. The voltage should never read zero, unless the sensor is damaged or not plugged in. Even on cold starts the 02 voltage would be .4-.6

Do you see any voltage at all from the 02 sensor on the PFC?

Double check your wiring. Also check you wiring at the ECU. Off the top of my head I forget which wire the 02 sensor is going into the ECU. I would check that one to if it is not the connection at the 02 sensor.

 

im gonna get the oem o2 sensor today

man this **** frustrates me

ill update ya guys
