replace both O2 sensors.

Yoyon · 10-26-2009, 12:35 PM

Wow they are like $ 200 each. Do u know where I can get them cheap or if they can be fixed?

Check ebay for used or new at much lower cost. I have installed both used and aftermarket, and all worked well.

The universal O2 sensors are the lowest cost, but will require splicing the wires from old harness to new sensor wires. Not hard, but does require crimping tool and care to get right wires matched. Most sensors provide guidance to wiring.

I would also suggest checking your wiring harness to make sure you don't have damaged wiring. Unlikely for both to be damaged, but also unlikely for both to fail at same time. You might also check your alternator's output voltage. Excess voltage might burn them out.

good luck

It says front or rear, I saw some wih2 and 4 cables, do u know which one I need?

Thanks

Check out http://www.rockauto.com/ or http://www.sparkplugs.com/

If you decide to go with the universal sensors, they are cheaper but require splicing of the wires like others have mentioned above. The OE identical sensors are direct plug in. I would recommend getting NGK or Denso.

Just one Question I am a Noob in this, where are the sensors located?

There is one before and one after the Cat. right?

TexasHonda · 10-27-2009, 7:58 PM

Primary is on the exhaust manifold underneath the battery. Secondary is aft of the catalytic converter. Check autozone for online manual help.

good luck

I just replaced both oxygen sensors for my 98 Acura TL 2.5.

I got my oxygen senors from http://www.oxygensensors.com. I was cheap and got the ones that needed to be spliced. They use crimped connectors and heat shrink around the connections.

Pre-cat sensor
-The sensor is located between the battery heat shield and under the engine at the exhaust manifold
-I had to remove my battery and the heat shield to get to the senor
-Get a Oxygen sensor socket at a place like Autozone. I was able to "rent" the tool by paying ~$25 and getting a full refund when I return the socket set. The socket is required because it as a gap to allow the wires to pass through so you can reach the bolt that goes around the sensor
-I used my breaker bar and was able to loosen the sensor
-The wires to the sensor travel down to be right behind the passenger tire/under the passenger door
-I removed the connector from the old senor and used it on the new one
-Installation is the reverse order

Post-Cat sensor
-The sensor is location around mid-section of the car after the cat
-There is a heat shield around the converter that I wasn't able to remove because the four bolts were rusted. You need to take off the heat shield to get to the sensor.
-I took it to Midas and for ~$34 they took off the heat shield
-Take the sensor off using a breaker bar and the oxygen senor socket
-The wires go up to the interior of the car and connect right under the passenger seat
