Santana chilly get started problems

A mileage of ck100 key programmer reviews about one hundred thirty,000 km of Shanghai Volkswagen Santana . Chilly difficult to start out the car symptom appears.

Troubleshooting : The fault detector detects no fault code storage. Look at the ignition technique , consumption pipe , motor timing and connected elm327 obd2 grounding strains, no exceptions. Cleansing the throttle and the ingestion pipe of coke plus the matching test , the fault stays. In accordance routine maintenance encounter, in case the above assessments had been normal , the chilly really hard through the commence is probably going to become way too lean mixture focus brought about . So whenever you get started to spray carburetor cleaner at the throttle , the motor can effortlessly start the device, which happens to be tricky to elucidate the explanations for starting off a cold car definitely is just too lean combination concentration.

After setting up the motor while in the motor , measure fuel force, normal ; motor flameout , strain scenarios to test the gas line , and also normal . After looking at the information stream engine is cold motor , find the coolant temperature is ninety five, although the actual coolant temperature is just about 20, infer coolant temperature sensor is faulty.The vehicle coolant temperature sensor has 4 terminals , which includes terminals one and 3 deliver coolant temperature signal to the motor control unit , terminals 2 and 4 offer coolant temperature sign for that instrument . Disconnect the ignition change, disconnected coolant autel md802 temperature sensor wire connectors, calculated by using a multimeter resistance coolant temperature sensor terminal 1 and terminal 3 amid 200 or so , which indicates coolant temperature sensor is broken.

Troubleshooting: Replacing the coolant temperature

Failure Analysis: Failure by car or truck coolant temperature sensor resistance drift prompted . When chilly starting up , coolant temperature sensor resistance about 200, the motor control unit mistaken coolant temperature ninety five, regulate gasoline injection pulse width is decreased , making sure that the focus of the mixture as well lean , ensuing in trouble starting off the motor . The car launch creader crp129 reason for the malfunction will not be complex, for knowledgeable routine maintenance staff may possibly begin directly from the coolant temperature sensor analysis , but owing to no fault code suggestions, the greater probably cause of the failure , from time to time there will be detours.
