Corolla egr valve?

Recommended Posts

Sorry if this is a dumb question but does my 2002 1.4vvti corolla have an egr valve? Asking because when connected to torque Pro obd reader app it shows "no info" under the egr section. I thought that with the euro4 regulations it should have and also if it does have one why isn't it showing up. 

I know the app works fine because in my friend's car a Suzuki Ignis 2002 it shows up on that OK. 

 

Just a bit confused that's all but any help would be great thanks.

The Torque Pro app is correct - I don't think there is an EGR on that engine.  In general, I don't think petrol engine designers from that period needed to resort to an EGR system to get emissions to the required levels; the Suzuki is the anomaly here.  It would be interesting to see why they went to that effort and expense.  Perhaps someone knows?  Perhaps the engine was designed principally for the US or Asian markets which had different requirements, and it was simpler just to leave EGR on?!

I think, given the age of your cars, that it was Euro 3 standards that needed to be met when new.

That makes sense and thanks for the reply. Was a bit confused after seeing the Suzuki reading it had one.

    1. 1. If you were to consider buying a Hybrid model over 5 years old, would you be worried about the reliability of the Hybrid system?


      • Not really as Hybrid systems are always reliable
      • Not if it had a Manufacturers Warranty on the Hybrid system
      • I would not buy a Hybrid model over 5 years old
