While driving, my engine suddenly lost power and the OBD scan returned faults on the EGR valve. Had the valve replaced, but the problem persisted. The sensors were checked using multimeter and it was faulty. Had more sensors in the engine room checked and many of them were faulty and had too low readings. Chose to wreck the car, as the machanics told me they had to remove the engine completely to replace all the faulty sensors because some of them were located behind the engine and unreachable from within the hood.
