Anyone able to help me out. Iv had my integra type R JDM DC2 fail its MOT on emissions. After a look at the exhaust iv notice that iv got a lambda sensor before the cat then a heat sensor after the cat. Problem is, the heat sensor has had the wire pulled off or caught on something on the road! Does anyone know where the heat sensor connects up to and will this affect my emisions?

 

you might find better results in the type r forum... welcome to HT!

 

Shouldn't there be loose wires under the car that has the same color wiring? Look for it!

 

Im guessing you are talking about your O2 sensors. If so, the connectors should be very close by and yes, those not functioning properly will affect your emissions. Do you have a check engine light on?
