Need help diagnosing P0401 on wife's 99 Sebrng JXi... 2. 5L V6
Code is for an EGR flow problem but where should I start testing? I found a vac leak(not egr related) and fixed it, reset CEL and light stayed off for a couple days but is back on now. I have not had a chance to get out the Mighty Vac to test the egr valve movement but will do so this weekend. Any way to test the flow sensor thingymajig on the front of the engine that the egr vac line goes to? I do not have a shop manual. I have searched many sights but have not found a single case of an egr problem on the 2. 5L.
All suggestions welcome.
Thanks,
Jim
