mrmay 0 Posted February 5, 2013 Hi I'm sure I saw it on here somewhere before but could anyone tell me exactly how many oxygen/ lambda sensors there are on a 1ZZ-FE engine and where they are located? As my engine management light came on today so I think this could be the problem, thanks. Quote Share this post Link to post Share on other sites
Devon Aygo 848 Posted February 5, 2013 PM me your chassis number and I will check as there is no definative answer the amount of sensors varies by model, market and by what emissions systems are fitted Quote Share this post Link to post Share on other sites
