[introduction]
Such problem has been encountered certainly in believing you drive, car is in start quicken or archives quicken when higher rotate speed is inferior, engine appears ringing " Da Da or Ka Ka " the sound that knock a crock. You may think fuel adds a fault, but change to still disable. Be maintained greatly by flicker to maintenance shop then, the likelihood improves somewhat at that time, but emersion of a few days of breakdown. This problem is actually probable be engine love a car explode shake sensor appeared breakdown place is brought about, tell you nitty-gritty today.
30 seconds fast read content of full text key:
1, explode shake sensor breakdown and fuel grade inadequacy, engine plays the breakdown phenomenon such as the crock similar.
2, most breakdown can generate breakdown code.
3, serious word quickens influence engine function and oily bad news.
4, those who maintain sensor installing hole is neat very crucial.
One, explode the action of shake sensor
Its installation is on engine cylinder body, with will detect the firebox in engine movement process deflagrates what cause shake. Transmit engine computer through electronic signal, after will realize ignition to shift to an earlier date with this or be being delayed, eliminate the engine that causes because of deflagrating to shake, the problem such as abnormal knocking.
2, explode the breakdown phenomenon of shake sensor
1, breakdown lamp calls the police: Most sensor attaint can accompany engine trouble lamp to illume.
2, engine power drops: As a result of signal deviation, bring about ignition to correct an error.
3, the abnormal knocking when engine quickens: Because eliminate,shake a function to lose, engine deflagrates will bring about " Ka of Da Da, Ka " abnormal knocking.
4, affect oily cost: Because ignition is couldn't get for a long time,amend correctly, bring about heighten of oily bad news.
3, do not want to be maintained blindly after engine abnormal knocking
1, condition of examination engine oil, antifreeze, eliminate problem of engine interior machinery to bring about abnormal knocking. Attaint meets most machinery to there also is abnormal knocking in the idling. And explode shake sensor attaint is the abnormal knocking when taking pain to is quickened in car.
2, change fuel, can choose gas station of another old brand to add note test of one box fuel, eliminate what benzine grade inadequacy brings about to explode shake.
3, computer detects, if explode,shake sensor damages thoroughly, engine ECU will store breakdown code. Observation will be relatively intuitionistic.
4, explode of shake sensor disassemble
1, disassemble the manifold that take energy of life
Explode shake sensor is installation is between the 2-3 crock of cylinder body the position, concealment quite. Disassembling so explode shake sensor when need disassembles fall into the keep out content such as gas manifold.
2, the note when disassembling
Disassemble after falling into gas manifold, the system that take energy of life was exposed, to avoid an eyewinker to drop air inlet duct inside, keep out should undertake 4 intake duct after we are disassembling, avoid an eyewinker to be dropped.
3, the examination of wiring harness
Before disassemble, we want above all to exploding shake sensor wiring harness undertakes checking, the outside force loss that whether the examination puts in interference to appear ruptures wait for a circumstance. Whether does plug exist corrode wait for a circumstance.
5, the condition of sensor is diagnosed
1, visual examination
We check the sensor that tears open debus to come above all the exterior, pursue on this sensor can see clear ablation case. The circumstance that ministry of wiring harness root and sensor connective position appeared to melt, interior reserves the possibility in the problem such as short circuit.
2, of avometer detect
Use resistor archives, will detect the block of sensor interior is worth change. Generally speaking after we express a pen on join, can put in certain block value, be worth the change that can have grain through shaking sensor block together. If be in open circuit condition from beginning to end, can judge the attaint of sensor.
6, the installation of sensor
1, the examination of installing hole
Explode the installing hole of shake sensor is the dimensional design that can have a level. Want to assure the accuracy that sensor signal collects, installing hole interior must keep neat, cannot any eyewinkers exist.
2, install essentials
The procedure of installation is simpler, but screw moment of force is to have strict level. Be tightened too and loosen to be able to cause the error that signal collects too, according to every model is different, leave factory the parameter of screw moment of force of moment is different also. Control in 20Nm generally speaking can.
Write finally:
Because engine explodes,shake sensor damages and cause without number of all sorts of case of the maintenance that cover a region. Car advocate once experienced such breakdown later, spent injustice money very easily. The hope carries afore-mentioned diagnostic kind, everybody can is opposite explode the trouble that shake sensor causes has an accurate knowledge, encounter problem hind in oneself so, with respect to handy. Did you learn?
