David Spilsbury Posted June 17, 2022 Share Posted June 17, 2022 Good Morning I was referred to The Honda Owners Club by Honda in Swindon. I own a 1995 Honda CRX (reg N753 EKP, engine no. D16Z6-4709549) which has failed its MOT due to high emission levels. I have been told I need a replacement catalytic converter and was given the name of Online Automotive. They have told me they can supply what I need but asked me 2 questions , neither of which I know the answer to as I am not technically minded. …does my car have a lamda sensor? …does it have onboard diagnostics? Can anyone help or offer any advice – I would be most grateful Thank you Dave 07867 663232 Quote Link to comment Share on other sites More sharing options...
Trevor Posted June 20, 2022 Share Posted June 20, 2022 Hi Dave Your car will probably have a catalytic converter with one lambda sensor and also it will more than likely have onboard diagnostics but in a very simple format (OBD1 or flash codes). The emissions failure may be down to something as simple as an exhaust leak which is drawing air, a perished vaccum hose on the intake or various other issue, not necessarily relating to the catalytic converter. An exhaust gas readout (4 gases + lambda readings) would narrow down the fault Quote Link to comment Share on other sites More sharing options...
