Honda Civic 1.3 Auto 1998 - catalytic convertor overheat #

Posted by Leslie Strong on August 4, 2009, 1:43 pm

Year of Manufacture *: 1998
Engine Code or Type *: EK2

Reported problem on this vehicle - warning light for catalytic convertor overheat comming on intermittantly (took a while to establish what this warning light was for as this is an import and the UK model does not have this light). It has no reported running defects.
We have established he vehicle is an import.
Any idead what can cuase this and also where the diagnositic plug is (also has engine light).
Emission readings are spot on.
Any ideas gratefully welcome.
Thanks

If you examine the cat. you'll see a temperature sensor fitted to it,often quite close to the after cat lambda sensor(if fitted).The overheat warning light is triggered by this sensor.I recently renewed one on an HRV-only £190 from Honda! I suppose you could fit a dummy resistor to the sensor plug,say 1kohm to stop the light showing on cluster.This car may have old style diag. plug above n/s kick panel i.e. connect the terminals of blue plug to get flash codes,and a three pin diag. plug for Honda tester.

Hi Leslie,
David is right about the price. IIRC, I think if you just disconnect the sensor (plug beside the handbrake lever) then the light will go off.

Never seen one where the cat had actually overheated - and the UK cars managed without a light.
