Although system designs vary, the heart of nearly all EGR systems is the EGR valve. Solenoid Valve Fail Guide. 5 flashes Twin communications fault Water By-Pass Control Fault. Low gas pressure, faulty gas valve, faulty hot surface ignitor or burner problem may cause this. All piping must comply with local codes and ordinances. High volts could mean there is a blockage somewhere within the EGR valve and no voltage could signal a problem with the valve and computer communication. coil II : R = 400 50 ? Test the electrical circuits by checking for short circuits, continuity (earth) and resistance (to earth). 74 . Check the fan: C8: Fan speed can not reached to target speed. Ignition Retry - If flame is not established on the fifth trial for ignition (initial try + 4 re-tries), the control de-energizes the gas valve and goes into lockout. The purge valve solenoid can be checked using a vacuum pump. Fan sensor not detected. A bad gas valve in a Honeywell appliance such as a water heater or furnace that is powered by natural gas can go bad and affect the performance of the unit. The control flashes a "4" on the LED to indicate ignition failure lockout. The valve operates similarly to the ones fitted in older models, only that an electronic EGR position sensor communicates with the vehicle’s computer for easier and faster control. coil I : R = 170 40 ? Remove the valve plug and connect it to a multimeter. Gas valve is functioning normally Gas valve is not powered. My Honeywell Water Heater Gas Valve Control is giving the 5 Flash Code "Sensor Failure". If it does not receive any voltage, you must check the wiring to the PCM. 5 – Replace any of the covers that were removed to access the electronic … What Does P0457 Mean? ... That will not always be detected by the ECU. The designation "B" refers to a certain position of the step-down EGR valve. Most of these switches are electronically controlled. 3 – Unplug the touch pad ribbon connector from the electronic range control. Gas cut off defective . FD 231: Mains power fault – electrical power interruption. False flame fault – flame detected after burner stop. ... with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 or The International Fuel Gas Code or B149.1 in Canada. ... valve electronic fault 3. 4. If your solenoid valve stops working, fails, over heats, buzzes, fails to close or fails to open, never worked, worked for a while or just died after years of use then this guide may prove helpful.. Solenoid valves are designed to control, divert or simply open and close against liquid, gas or even vacuum media. 72. Many Netaheats have been scrapped with suspected gas valve failure when the fault actually lies in a soldered joint on the control board which fails from heat stress. Loose or corroded wiring can cause your valve to remain closed. Fan motor current detection failure. A stored code P049B means that the powertrain control module (PCM) has detected a malfunction in the exhaust gas recirculation (EGR) system "B" flow for a particular step-down setting. Fault Location Probable Cause; P0402 : Exhaust gas recirculation (EGR) system -excessive flow detected : Hose leak/blockage, basic setting not carried out (if applicable), wiring, EGR valve… Gas Control electronic fault detected. 8 RED FLASHES: This fault is indicated if the flame is lost 5 times (4 recycles) during the heating cycle. Replace and repair the parts of the water heater with caution. No flame detected: 5 02: Flame detected with gas valve closed: 5 04: Flame lift: 5 P1: 1st Ignition Failed: 5 P2: 2nd Ignition Failed: 5 P3: Flame cut-off: air inlet/ flue gas outlet faults: 6 04: Insufficient fan speed: 6 10: Thermofuse open: multi-zone heating faults: 7 01: Zone 2 … Read the code as p0401 P0401 - Generic Type Powertrain - Auxiliary Emission Controls - ISO/SAE Controlled Description Exhaust Gas Recirculation "A" Flow Insufficient Detected Wondering if any others have had similar before I contact Vw?
