80K miles on my 98 3.2 and my CEL turmed on this morning.

P0153 O2 Sensor Circuit Slow response (Bank 2 Sensor 1)

Help!

I cleared the code by using an OBDII reader.

I have not used the car yet.

Thanks in advance.

have you replace your o2 sensor? bank 2 sensor 1 is on your driver side..manifold

Mandy

Both sides (O2 sensors) were replaced by Acura about 2.5 years ago, when the car was 60K miles.

Mandy

Does this mean I have to replace this O2 sensor again?

It's likely the sensor is faulty or contaminated. I would suggest pulling the sensor connector, checking, and cleaning any oil or dirt. Reset ECU and see if same code appears. If yes, a new sensor is indicated.

good luck

Mandy

Thanks, how do you reset ECU?

Mandy

Bank 2 Sensor 1 is DRIVER side, right? What do I use to clean sensor?

KrayzieDxC

ECU is under the carpet of the passenger side, and yes the sensor is on the driver side

TexasHonda

You don't pull the sensor. If it's contaminated, it can't be cleaned to my knowledge. Occasionally, dirt and oil will contaminate the connector to the O2 sensor and cause the signal to be degraded. Only disconnect the connector, clean contacts, reconnect, and reset ECU.

ECU is reset by pulling the BackUp fuse in the underhood fuse box for 20 secs, or disconnecting battery negative cable for 20 secs. You will need radio code to restart radio and all radio presets will be lost.

If code comes back, you'll need to replace the O2 sensor at that time.

good luck

Mandy

How much is a sensor? Is it the same as the left anf right side? I have cleared ty code through an OBD II code reader, is this not enough? I need to reset the ECU? Thanks.

TexasHonda

No, resetting w/ a code reader is fine.

O2 sensors range from $25-$100, depending on whether they are direct replacement (wire harness complete) or universal (cut/splice wires required).

Check ebay and internet for range of prices and products.

good luck

Mandy

Thanks...so, I was due for an Air filter change anyway, I replaced the air filter, applied some electrical connection paste (usually used for bulb connections) on the O2 sensor connector.

Cleared the code through the OBDII, took the negative terminal 1 minute.

The CEL has not lit back up, one day of use.

We will see.

Thanks again.

Mandy

6 days after no CEL....knock on wood.

Mandy

So far so good............knock on wood.....change filters every 15K...helps!

Mandy

Well, it came back yesterday, same code. I cleared it using the OBDII. Let's see what happens....

Mandy

I will have to check ebay....there was an ebay OEM supplier which sold DENSO O2 sensors...

Mandy

Where do you guys get your O2 sensors? I have been checking OEM Denso O2 sensors, they are like $120 from ebay re-sellers. Dealer wants $200+. I see replacement O2 sensors at $50 shipped, non OEM, universal type.

I have same code. It all started after I washed engine bay couple of weeks ago. First time it came ON with half mile drive after I washed the engine. I cleared it right away. Now it came back ON again after 2 weeks or so.. Looks like I have to take the connector off to clean it up..

Mandy

Mine has not returned for some time, knock on wood. I usually apply a thin coat of bulb grease on the connector.
