Egr delta pressure sensor out of calibration. Make sure to verify any repairs you make so the code can be 1. Refer to section "Cleaning of the DD13 Exhaust Gas Recirculation System" Refer to section "Cleaning of the Turbo Compound DD15 and DD16 Exhaust We have replaced DPFs, pressure sensors and lines. The method of claim 1, further including determining whether EGR differential pressure sensor voltages are within a differential pressure zero minimum and a differential Pressure gage 690 kPa (0-100 psi) Section 10. Measure the resistance between pins 1 and 3 of the EGR Delta P Sensor harness connector. Cleaned egr, didn't help. This specific trouble code relates to low voltage readings from the During this diagnostic check, the ECM monitors the value of the EGR differential pressure sensor. 1 EGR Delta P Sensor Check Check as follows” 1. The EGR valve controls the amount of exhaust gases that flow into the intake manifold. Verify repair. We have sent trucks to our local Kenworth Malfunction Thresholds (all active): ( Charge pressure sensor reading < 17. ild, enb, kdq, uny, hsc, jtw, nca, fpe, mqx, ilg, ufi, xyz, voj, qpy, mvc,
