Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / February 2008mazda 626 2002 egr valve problem
Hello my car did not pass emissions, my mechanic replace the egr valve but this did not fix the problem. Has anyone had a similar problem any recommendations? thanks. > Hello my car did not pass emissions, my mechanic replace the egr valve > but this did not fix the problem. Has anyone had a similar problem any > recommendations? thanks. Is the check engine light on? If so, what are the diagnostic codes? And why did your mechanic replace the EGR valve? Chris >Hello my car did not pass emissions, my mechanic replace the egr valve >but this did not fix the problem. Has anyone had a similar problem any >recommendations? thanks. Not without seeing the measurements. What were they, how far out of limits were they, and how? --scott  Signature"C'est un Nagra. C'est suisse, et tres, tres precis." Thanks for all the replies, it was error code 0400. It went away after cleanning the corrosion in the egr. > In article <64a589a8-3309-428d-bbcc-e8d1ad14c...@v3g2000hsc.googlegroups.com>, > [quoted text clipped - 7 lines] > -- > "C'est un Nagra.

That's not what I asked. That's the error code that the computer recorded, not the measurements of the exhaust that the emissions analyzer recorded. The emissions analyzer measures a lot of different things. Knowing what measurement is out of range and how far it is out of range is necessary to know what caused it. --scott Signature"C'est un Nagra.

OBD-II codes are 5 characters. It was probably P0400, but we need to know for certain. Chris |
