Question 1 of 10Automatic Gearbox Fault Diagnosis Challenge
Idyllic quiz Automatic Gearbox Fault Diagnosis Challenge All 10 questions
- If an automatic gearbox is stuck in 'N' and no shift is possible, but the problem persists even after confirming mechanical actuation, what is the most probable cause?Hydraulic pump defective · Shift / selector lever defective · Pressure sensor defective · Accumulator defective
- What symptom often occurs due to an automatic gearbox's internal sensor failure?Inconsistent gear shifts with delays · Pump runs constantly · Starting is almost impossible · Gearbox stuck in 'N' and blocked
- Gear selecting is not possible via the shift selector lever but is possible using diagnostic software. What is the most plausible fault?Gear position sensor failure · Hydraulic pump defective · Shift / selector lever defective · Pressure sensor defective
- If an automatic gearbox's hydraulic pump runs only briefly, but the system does not hold pressure, what is the most likely cause?Pressure sensor failure · Hydraulic fluid low · Pump relay defective · Accumulator defective
- What should happen to the system pressure after the engine is switched off?It should drop only 2-3 bars and remain steady · It should increase slightly · It should remain completely constant · It should drop rapidly to zero
- What often causes the system to turn off unexpectedly, even when parked with the ignition on?Electrical fault in control wiring · Faulty ignition key · Accumulator defective · Pressure sensor defective
- Which component failure is indicated by clutch chatter and difficulty starting, but only at high speeds?Pressure sensor defective · Gear position sensor failure · EV0 defective valve of the clutch control · Accumulator defective
- If there is a flashing gear indicator and gears can be skipped with a sense of delay, what is the most likely issue?Pressure buildup · Sensor failure · Shift / selector lever defective · Hydraulic pump failure
- When troubleshooting a gearbox issue with no error codes, what should be the first step?Do a visual exam looking for leaks and broken wires on the gearbox · Calibrate the clutch · Change the gearbox oil · Replace the hydraulic pump
- What is a likely indication that the accumulator is defective, distinctly affecting the gearbox performance?Hydraulic pump runs constantly · Inconsistent pressure levels · Gears are ejected during driving · Pump runs only briefly
