Denso234-4209 Universal Oxygen Sensor with 11.5” 4-Wire Harness (connectors not included)

Denso234-4209 Universal Oxygen Sensor with 11.5” 4-Wire Harness (connectors not included)

Q: will Denso 234-4209 Oxygen Sensor work for Toyota sienna

Amazon allows for a car's make, model, year, etc. to be entered at its site to find out if a particular part will fit that car or not. Please do so to find out if Denso 234-4209 oxygen sensor will fit your car.

Q: It does come with a connecter? So I'm buying what exactly?

You have to cut the connector off the old part & splice the wires to the new O2 sensor. Part comes with wire crimp fittings.

Q: Is this for upstream or downstream?

To answer your question correctly I would have to know the vehicle year, make, model to complete your request. Most O2 sensors are for the front or back with the wiring connector being different, so if you do not find a match by running your vehicle off the Amazon site call Auto-Zone or look on their site to confirm the correct number for the sensor. I will warn you that using any aftermarket sensor is not the same as OEM which means the milliamp output is not the same by the aftermarket part and may not clear the code in your vehicle.

Q: What is the heating coil resistance? I installed on the car and got check engine code. Measure the heater resistance 29Ohms, that seems too high.

It is a bad reading on your part, or the sensor is bad
