Having problems with your 2002 Mazda Tribute ?
Hi my fault code is p0401,egr insuficient flow detected.light come on about every 2 days& wont go off unless use a scan tool.have fitted a new egr valve but still comes on ,any ideas howard
Just change the Egr Pressure Feedback Sensor, I recomed to buy it at O'Reilly Auto Parts it sells for $36.99 + tax and its Limited Lifetime Warranty, others 1 or 2 year warranty.
Maybe a short? possibly a bad connection at the valve.
