A 2007 Concentration sedan vehicle, the motor starts jogging effortlessly, following touring a long way in the human body shake.

Troubleshooting:The very first incidence of this failure, a repair service store for upkeep, the plant exchange the spark plug, the fault disappears, zed-bull traveling nearly 600km (one thirty day period) right after failure recurrence. A 2nd to find a new upkeep depot mend, alternative of high-voltage ignition coil plant, then the situation is solved, traveling for two months, right after about 300km fault relapse.

3rd re-selected a maintenance shop for upkeep, the plant to interchange the ignition coil, the fault disappears, but a few days after multidiag 2013 the failure of recurrence. During the case in the homeowners nearly discouraged, consider holding the mood, introduced by a buddy to our repair service shop.Fault detection:Move one: decoding equipment with 431 study fault codes, multi-cylinder misfire fault code display screen.

Analysis: cylinder misfire is really a common fault multi-cylinder motor, its detection and diagnosis of car fault analysis function can be a required autel ds708 portion. Misfire motives but you will discover many different create, like the ignition method (spark plug fouling, the ignition electricity is reduced) failure thanks to leakage ensuing in very low tension cylinder compression, etcetera., nevertheless the fact will not be achievable to detect the phenomenon of generate every fireplace kind of fault resources individually detected.

Multi-cylinder misfire failure may perhaps result in: person cylinder high-pressure point line off or dampness leakage; personal spark plug soaked, abnormal carbon leakage or insulation injury; spark plug electrode hole is just too tiny or as well substantial; cylinder stress is minimal, x 100 key programmer valve Mifengbuyan, piston ring put on critical, cylinder gasket damage etc.Normal aspects of multi-cylinder misfire detection circuit, ignition process, gasoline method, oxygen sensors, cylinder pressure, throttle placement sensor, crankshaft place sensor, temperature sensor.
