Where is bank1 senor1 o senor located? - 2006 Hyundai Sonata

P0340- Camshaft Pos Sensor Circ Error (bank1/1Sensor) Here is your code results and no the sensor is not in the distributor. Looks like the #1 senor is bad.

It is possible it is in the passenger side exhaust manifold.

that would be the o2 censor on the car it has to do with fuel millage and how good of millage that you get. it probable has the heating element burned out in it and needs to be replaced right a way

Drivers side

this car has only 1 bank ... front o2 senor is the one bank1 sensor1
and the rear one will be bank 1 sensor 2

hope it helps rate it

bank #1 sensor 1 front.bank #2 sensor 2 is back.

YES

This is a 4 cylinder right? Open the hood and look down between the engine and firewall, this is behind the engine. You will see the exhaust pipe, follow the exhaust pipe up to where it is bolted to the exhaust manifold. You will see the upstream O2 sensor screwed in there, more or less horizontally with wire connector pointed at driver side of car. Now get under the car and find the catalytic converter in the exhaust pipe, a big bulbous thing, the downstream O2 sensor will be after the converter, but before the muffler and will also have an electrical connection.

This car has a transversely mounted straight six I believe, which is really unusual, but that means it only has one bank, so "bank 1, sensor 1" will be the upstream O2 sensor (between the engine and the cat) and "bank1, sensor 2" will be the downstream sensor (behind the cat).

Bank 1 is the drivers side. But the sensor you want is the one farthest back, right before the muffler.
