Mrs P came home last night and said the orange engine symbol show up on the dash, which is the malfunction indicator lamp.  She drove for about three miles with it on and said the Rav was running as normal, no juddering or loss of power nor any other warning lights came on. So i know it could be a list of things but anything i could check and try that might give a simple solution? |

Do you have a code reader Paul?

If you invest in a OBD II engine code reader you will be able to workout what code is coming up, my guess is a lambda sensor in the manifold has failed. With the warrenty is that half the cost of repair or not covered at all ?
Lots of code readers on Amazon from £20 upwards ..then you have one for life 👍🏻

Yes David i do which i forgot about so put it on and it wasn't going through the sequence as in the manual but let it do it's thing then pressed enter and came up with P2238 01/01. Pressed scroll and that was the only P code that came up? I have told WCVC and they are looking to see what work they have done to it before we had it so am waiting to hear back. |

Could just be a fluke, Paul. The EML lit up on ours a few weeks back (I think it was P2238) but I put it down to the fact that our daughter had been using the car for the previous month or so and had only been doing VERY short runs so the engine never got up to temperature.
I cleared the code and invested in a bottle of Millers fuel system cleaner from Halfords. Everything's fine since. :TU:

Code P2238 is lambda oxygen sensor in manifold 👍🏻 As suggested use reader to clear code see if it comes back again 😎 |

Not sure about the short trips Jim as Mrs P has been on longer trip of about ten miles when it came on last night, but her trip to work is short every day about 2.5 miles, but how did you clear it as she said it was running normal still? |

Are they easy enough to do or is it a garage job? How many of these sensors are there ? |

Lots of code readers on Amazon from £20 upwards ..then you have one for life 👍🏻 Just looked at the warranty Bob and yes the oxygen sensors are covered at 50% cost upto the value of £500. |

Ours was running normally, too. Bear in mind that these sensors work by measuring a tiny difference in current flowing through them caused by the mixture/oxygen content going out of the permitted range. So, it is possible to get the EML triggered by a one-off event that doesn't necessarily arise from a fault - hence my crude definition "fluke". It could be caused by moisture inside a connector or a bit of creeping corrosion in a connector or an earth - it's not automatically a sensor that needs replacing.
These electronics aren't fool-proof. I once had a new Vauxhall Omega that would light up its EML occasionally for no reason. In those days you had to take it back to the dealer to have it diagnosed and every time there was no underlying fault; the car always ran fine and never went into limp mode.
You may need a new sensor but I would suggest that you erase the code and keep an eye on it for a while to see if it returns before going out and buying a new sensor.

Thanks Jim :TU: how do i clear the code do i disconnect the battery as there was no option on the scanner i have, i don't think just enter and scroll buttons? |

On the scanner tool in the options There are read codes, clear codes etc ...clear code and see if it returns .
"Are they easy to replace" Well yes and no as it’s all about having the tools for the job . The mk2 RAV4 petrol engine had two types of exhaust manifold, I’ve just realised my car has a single Catalytic converter with one Oxygen sensor...yet my two 2004 models I had previously has twin cats with 4 sensors .
This could be a job you pay a local garage to do and sent WCVC the invoice .

Cheers Bob think a garage can do the job as i've just had a reply back from WCVC and it is covered at 50% parts and labour, so gotta find a good local garage :TU:
