Bank 1 is the O2 sensor on the exhaust manifold just about where the exhaust pipe connects to the exhaust manifold.

1997 honda accord. 4 cylinder automatic. Probably a simple thing. But check engine lights on. Ran the test and it says o2 sensor heater circuit(bank 1 sensor 2). My questions are. What is this? Where is...


02 sensors are OXYGEN SENSORS positioned in the
exhaust....they measure the air fuel ratio. Google 1997
Honda Accord 02 sensors...there are many links pertaining
to this. Do you have a Haynes Manual for your car? A good
thing to have.

Scanner show 02 sensor needs replacing, but which one?


P0141 indicates oxygen sensor 2 in bank 1. Bank 1 is on the side of the engine where the first cylinder is.

Your firing order (and the location of your cylinders) can be found here:

Bank 1 o2 sensor 1999 honda accord lx v6, i need the location to change it. i can not find it in the front of my car


Bank 1 is at the back of the engine compartment next to the firewall. You'll need to know if you need to change (bank 1 sensor 1), or (bank1 sensor2). Sensor 1 is located in the exhaust system between the rear cylinder head and the catalytic converter. Sensor 2 is after the cat in the exhaust system after the cat.

I have an 02 accord ex 4 cyl. that need the down stream o2 sensor replaced, where is the pigtail located ?


as you are looking at the exhaust you will see the catalytic conveter (large very hot peice) behild it is the downstream sensor the pig tail runs out of the back of the sensor, usually plugs and unplugs right the under the car if it runs through the floor board then you will have to pull the seat and go under the carpet

Oxygen sensor replacement


you need to rent an 02 sensor socket and use a ratchet and the socket to remove it, there are two on the exhaust pipe one before the cat, you can see it on the exhaust pipe and one after. normally the 1at one goes out. cost $75.00 please rate if helpful.

Flashing green s on the dash


A green flashing "S" is similar to a check engine light. It is telling you that something in or on your transmission is not functioning correctly, such as the speed sensor or shift control solenoids. If it starts flashing and the speedometer stops working or the transmission shifts weird, take it to a mechanic.
