Howell TBI O2 Sensor
The O2 sensor went out already went out on my 1 yr old Howell TBI system and the ECU is shooting code "13". I have the heated version and it it located in the header collector just before the muffler and run a 304. Is this normal? I thought those last many years. Is it possible to fool the ECU into thinking it is working? I am under no emissions testing and do not have to get the Jeep inspected ever again.
