just a quick note: bank 2 is LEFT side (drivers) on a rear wheel drive vehicle ,on front wheel drive vehicles it would be the front side when looking down from the front of the vehicle ,Sensor 2 is after the cat converter! if you replace that sensor, clear the codes or have someone clear them for you and you should be all set

Hey James==It would help if you stated what kind of car you have. Joe
the 2 of bank 2 is the 2nd oxygen sensor that is located after the catalytic converter.usually closer to the tailend of the header pipe.
The sensor I believe you are looking for is in the exhaust pipe or exhaust manifold, usually the right bank which is on the right side of the car (driver is left), or close to the firewall if engine is mounted sideways. Some cars are equipped with a sensor behind the catalytic converter that tells the computer the HEALTH of the converter only. It has nothing to do with running of the engine per say.

Bank 1 is which ever side has cylinder 1. It could be left or right. Bank 2 would be the other side. Bank 1 sensor 1 would be before the catalytic converter. Bank 1 sensor 2 would be after the converter. The same applies with bank 2.

This is referring to the first Oxygen sensor, located on the exhaust manifold. It either indicates a short in the wiring or the sensor needs to be replaced altogether.
The Diagnostic port, looking from front of vehicle, is located on the drivers side rear corner of the engine compartment
A car owner should know the location of the diagnostic port in their car. The diagnostic port in a 1994 Wrangler would be in the engine compartment, near the firewall.
Beside the battery in the engine compartment. Labelled DIAGNOSTIC.
The diagnostic connector on a 2001 Honda Accord can be found in the engine compartment. The connector is located on the passenger-side in front of the firewall.
OBD P0645 indicates a fault in the A/C clutch relay.OBD P0645 indicates a fault in the A/C clutch relay.
It is very easy to reset a check engine light on a 1997. The light can be reset by putting the restet tool into the diagnostic port. The diagnostic port is located right beside the hood release latch.
The diagnostic connector is under the hood. It is located along the engine wiring harness.
There are two diagnostic connection ports, there is a diagnostic connection port below the dashboard on the drivers side. A second diagnostic port can be found in the engine compartment on the firewall.
Ducato petrol engines, The DLC is located very near the air filter. in the engine compartment.
the OBDII terminal is located on the driver side in the fuseblock panel. There is another diagnostic terminal located on under the the same dash panel just a little further under the dash it is a round terminal looks like something for Toyota to hook their scanner into. Then their is one under the hood about midway back and in the center on top of the engine that is for engine diagnostic . your welcome Jeremy Hadley Arab AL.
The OBD-1 diagnostic connector is located on the back of the block beside the starter. A series of jumper wire locations are used in conjunction with watching the CHECK ENGINE light.
P0135 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1) Bank one is drivers side. Sensor 1 is the one closest to the engine.
it is a high voltage sensor...but i would like to know where it is located
The diagnostic port is located in the engine bay next to the front left wheel strut top (I believe that's what it's called). Also, you can find it in front of the brake fluid reservoir. In addition, facing the front of the car, you'll find it to the right of the engine (your right facing the car). The top of the cap should say "Diagnostic Port".
air flow is usually connected betwen the air box and engine, lambda sonsors are on the cat or exhaust, both can appear as an O2 fault on most diagnostic readers
The diagnostic connector is typically located under the instrument panel, above the engine latch, and may be under an access port.
On a 1990 Ford Thunderbird : There should be an EEC TEST connection in the engine compartment for the OBD I , EEC IV system
The diagnostic code P03xx is not specific to one vehicle manufacturer. In fact, most codes starting with a P are not manufacturer specific. In the case of P03xx codes, the P03 indicates the issue is with the ignition system. The xx in this case, assuming it is between 1 and 12 indicate the cylinder in which the problem ocurred. P0305 indicates a Cylinder 5 misfire has been detected. For a complete list of OBD-II Diagnostic Codes, go here: http://www.obd-codes.com/trouble_codes/
if there is engine oil in the antifreeze generally indicates a cracked head on the engine
That is the check engine light.
I believe there is an ( EEC TEST ) connection in your engine compartment , by the power distribution box ( OBD I / EEC - IV )
It is the port, where a diagnostic machine can be hooked up. The diagnostic will read codes from your vehicles computer. For instance if your check engine light comes on, you can plug the diagnostic machine into the data port and it will tell you why the check engine light came on so that you can get it fixed.
The DLC (Diagnostic Link Connector) should be located in the engine compartment on top of an inner fender close to a relay/fuse center. It may be snapped into a protective cover.
