oxygen

I have got an error indicating: Error: O2 Sensor circuit slow response Bank 1 Sensor 1 (Upstream / Pre-cat) signal rate of change below threshold. Anyone able to assist me with getting the Mercedes / Bosch part number please? Vehicle details: 2011 E200 CDI (no stop / start) Chassis...

Morning all, I've got a code saying the o2 sensor is bad on my CLS 320 CDI so I've bought a replacement and the tool to change it. I've been googling furiously to get an idea of the location of it and come up short, other than somewhere on the exhaust system. Can someone recommend where I...

I wonder what kind of oxygen sensors there is on 1998 - 2000 eüro market W202 C43 AMG? Do we have wide band oxygen sensors or narrow band oxygen sensors on our W202 C43 AMG? Eüro/Djapan/Australija market C43 AMG had only 2x oxygen sensors without CEL option, where the US market cars had 4x...

Hi All Hoping someone can help with advice on a problem I have with my C230 Automatic 2008 W204. I am based in Singapore but from UK with a UK Spec car. As with everything here car costs are horrendous along with repair and even from the main dealer you can't get honest advice. So my car...

After a long search on what's causing fuel smells in the exhaust and the engine not running smoothly on operating temp, I decided to replace my oxygen sensor. To my big surprise, only the connector (see picture) is installed. The hole where the wires to the sensor are supposed to be is sealed...

Good day everyone, Just thought I'd start a discussion on this relatively new (to me at least) method of engine cleaning. I'm referring to the use of chemicals that's made up of mainly oxygen and hydrogen from my understanding, which is then fed by a machine into the engine via the fuel...

Anyone know the effect on MPG a faulty sensor will have?

Hi, I can't seem to locate any oxygen sensor in my 1994 E220 (W124), with the M111.960 engine. There is definitely none all along the length of the exhaust, so for a while I thought it was on the manifold, as it seems from the EPC image attached. Today I looked more carefully and found that...

Recently had my 07 E320cdi on star after an engine diagnostic light came on and car went into limp home mode. Light now turned off but I know that the problem may well resurface and I would like to preempt the problem by buying the part. Am I better going to MB directly or is aftermarket...

Hi I have a 2008 W211 E320 CDI (V6) with 50k miles. I have noticed some performance issues recently with a loss of power and quite a bit of soot from the exhaust. I connected a OBDII tool and pulled the following errors: P0130 P0135 P0030 P2A00 I think that these all seem to point...

i am in need of an o2 sensor (before the cat) but there are quite a few on ECP website with very minimal price diffrences. can you point me to the correct sensor please....my reg is p936ado and my engine code is 111945 22 006247 thank you very much in advance.:thumb:

No idea of fitmet, Am told this is for CLK, SLK, 2.3K Engine (2001) for the Rear sensor. Not sealed but brand new!

Had my clk 350 sport for two weeks now and today gave it it's first long run about 2 miles from home engine managment light came on and made it home .Called mercedes 24 service and they had a mechanic with me within 1 hour he done his fault diagnosis and told me it was one of the sensors and put...

As per the title. I have more than a hunch that my left bank oxygen sensor might be defective. If I replace this does any of the car's brain need resetting to clear the fault codes logged or will the new oxygen sensor just work and my car start breathing out lovely clean air again?

Guys have been advised i need to replace the upstream oxygen sensor, any ideas on how to? Where abouts is it, and what else do i need to remove in prep for it? Any hints/tips gladly appreciated. Apparently this could be causing the misfire on my car when its idling.....:crazy:

Morning All, still have ongoing issues with my C220cdi 2004, Car has a misfire since the exhaust manifold was taken off. Basically i have had star machine on it and it diagnoses a fault with injector no.1 and oxygen sensor, have replaced injector which made no difference, had the old injector...

:bannana:Could someone explain the reason for Presence of Oily substance in Connector of Oxygen Sensor.:bannana:. I have noticed this while changing the Sensor. Interesting thing is Wires to sensor are all dry and coming from ECU is dry. I am talking about sensor which is near to engine on...

This forum is not a cry for help (makes a change) but rather to inform and hopefully help others with similar problems. Over the last few months my car has not been driving as well as it should, not a major problem but it did get a little irritating. When casually pulling away or casually...
