Review on Pressure Feedback Keenso Exhaust Recirculation by Efrain Khan

rubbish! Checked my entire exhaust system, found the EGR pressure sensor is faulty, the sensor output voltage was too high, measured at 5V. Replaced the EGR sensor with this one, the output voltage is 0.91V within tolerance. Driven the car to the coast and back and stopped at the shop; On the drive home the check engine light came on. I came home, the output voltage was measured at 4.78V (should be between 0.2V and 0.95V). Traveled an incredible 553 miles, that's 29 hours since installation. Garbage! Nobody testing this thing, I mean it only took ONE DAY!
