Engine Light Issue

[Andy M]

Hi my engine Light comes on intermittently. Diagnostics reveal it's O2 sensors issue. I assume replacing all O2 sensors should resolve this issue. Any comments. Also where to get the right sensors for my 2004 campervan

Probably, but why not replace just the one that's broken?

I purchased a compatible O2 sensor from a user group recommended parts dealer. However the engine Light continues to display the same error code intermittently. I was advised only an original Toyota part would fix the issue and that does appear to have been the case. It was twice the cost but would have cheaper if I had done that straight away rather than numerous attempts. So lesson learny

when it comes to sensors then oem parts would be best, but there will be sources that will be cheaper if you spend the time looking around.

 

i cross ref parts across different Toyotas and found that buying parts from a Rav4 which had compatibale parts was cheaper. For instance i saved a packet when i needed 2x front wheel hubs which were for a Rav4 and same part number.

 

Also if i am buying oem i use Toyota Parts direct or even Lexus Parts direct which had different prices, same company but different car, but same part.
