Question about 2003 Honda Element

1 Answer

I found out my O2 sensor after the catalytic converter was bad on my 03 Honda Element. I changed it out with a Bosch OE Smartlink connector and the light didn't immediately go off. Do I need to wait a few days, or does that mean they sold me the wrong one?

You don't change an O2 Sensor based on a code
The code only points to an area of a possible issue,such as an out of range sensor.
You then diagnose and test,in your case the O2 Sensor,and replace only if it fails to work correctly.
Why wouldn't you clear the code after replacing,if it was still on,when you started the engine

What might it cost to replace an O2 sensor on a 1998 S70 Volvo GLT, approximate range (in the San Francisco area)? Thanks!


This should only take about a hour to change plus the sensor cost I think this car has 2 o2 sensors but i would recommend that you a OE type sensor (bosch) they are not cheaply made But here in DIXON I would do this for $198.00 for sensor and $60.00 labor total $275.00
If sensor is stubborn and removal hard I suggest to spray sensor with a penetrating oil for couple times this will soak into the threads to be removed easier

2003 honda element code po141 o2 heater circuit bank 1, sensor 2 which sensor is this.


This sensor is "downstream" of the catalytic converter. On some Honda installations, this means the sensor is placed halfway down the side of the catalytic converter.

Error code" catalyst syatem efficiency


This usually indicates that the catalytic converters are no longer working. This can be confirmed by watching live O2 sensor data on a scan tool. If the downstream oxygen sensor is switching similar to the upstream O2 sensor than the catalytic converter has gone bad.

When you decide to fix it go with a direct fit cat from a reputable manufacturer or get the O.E. cat from the dealer. This will save you from many headaches!

Troubleshooting P0420 OEM Brand Honda A/F ratio concern Air leak near H2OS(heated oxygen sensor) Ignition system concern faulty catalytic converter


P0420 indicates the computer thinks the catalytic converter isn't working as well as it should. This is determined by the PCM evaluating the switch rate of the front and rear o2 sensors. Once the rear o2 sensor switch rate reaches a point close to the front o2 sensor it sets the code. This can be a result of degenerated catalytic converter, or in some rare instances, bad o2 sensors. In most cases repairing this condition requires replacing the catalytic converter with an OEM unit. Aftermarket converters don't have the same quality and quantity of the precious metals that make up the substrate found inside. This usually results in the code setting again in just a few months.

WHAT CAUSED ERROR CODE P2097 ON 2005 CARAVAN? ENGINE LIGHT DID GO OUT.


The code found P2097 is 1/2 O2 sensor rich (downstream- below the catalytic converter). Your previous code is related to the same O2 sensor.

I would recommend replacing the O2 sensor then go from there. If it returns then you will have to start testing the wiring. I would recommend changing the O2 sensor now if you are able to.

It is simple to replace and easy to get to. The trip would be a good chance after the repair to see if it returns with the number of miles you would be driving.

1. Oxigen Sensoir connector
2. Catalytic Converter
3- Downstream Oxygen Sensor
4. Engine Harness connector.

It can have an effect on engine performance and fuel economy. So the sooner you replace it the better. I dont believe it will leave you stranded on the road anyway by any means so I wouldnt worry about that if you arent able to replace it right away before the trip. If you need more help or have more questions then let me know and I will help you further.

Hope heplp with this (remember rated this post).

My oxygen sensor on my 03 Honda Element failed. How do I replace it myself?


Your Honda has two O2 sensor's, you will need to find out which one is bad, you have an upstream and a downstream, the upstream is the one between the exhaust manifold and the catalytic converter, and the downstream is the one after the catalytic.It's best to have an O2 sensor socket but if you don't have one an 7/8 wrench will work, disconnect O2 sensor harness and unscrew right out, install new sensor and reconnect harness.
