Common causes include a faulty electronic pressure control solenoid, transmission fluid pressure sensor, hydraulic blockages inside the internal transmission fluid passages, mechanical internal transmission failures, low transmission fluid, dirty or contaminated transmission fluid, a faulty PCM or transmission control module. How do you troubleshoot P0847 ? The valves of each cylinder are kept closed using a pair of arms that replace the conventional engine's roller-type rocker arm. P0847 code one of these arms follows the cam profile while the second arm connects to the valves. During normal engine operation the two arms are joined by a locking pin.
