Hi
Does anyone know how many wires there are in the O2 sensor on a 2003 Sonata
?
I see some on Ebay that are much cheaper than the dealer and they have 2
wire and 4 wire types.
Thanks
Jc

 

All 2003 Sonatas use four wire oxygen sensors. If someone is selling
2-wire sensors for a 2003 Sonata, you should take that as an
indication that you should stay away.

Additionally, there was a change in ECM logic and oxygen sensor design
for the V6 partway through the 2003 production run. Even if you
purchased a four wire sensor, there’s no guarantee it’s correct for
your car.

Furthermore, many Hyundai oxygen sensors have a bias voltage. I’ve
heard of problems using aftermarket oxygen sensors
