What are the effects of a faulty sensor on a Sagitar?
2 Answers
The effects of a faulty sensor on a Sagitar are as follows: 1. Symptoms of a faulty speed sensor: Unstable engine idle; momentary stalling or engine shutdown when starting or decelerating to stop; reduced engine acceleration performance; deviation in the speed display on the dashboard; engine warning light illuminated; 2. Manifestations of a faulty throttle position sensor: If the throttle position sensor is misadjusted, it cannot ensure the correct ignition timing and air-fuel mixture ratio. The throttle position sensor should be precisely adjusted to the specified voltage reading. If adjusted too low, knocking may occur during acceleration due to insufficient exhaust gas recirculation (EGR) system response. If adjusted too high, the EGR system reacts too quickly, providing excessive exhaust gas, which reduces power; 3. Manifestations of a faulty coolant temperature sensor: If the coolant temperature sensor malfunctions, the engine may exhibit unstable idle, misfires, stalling, or increased fuel consumption. A multimeter should be used to test the sensor's resistance values at various operating temperatures as specified by the manufacturer.
My old Sagitar gave me a real headache when the sensor went bad the other day. The car would jerk and hesitate like it had asthma every time I stepped on the gas. The engine warning light on the dashboard was glaringly bright, and the repair shop's diagnostic scan showed a faulty mass airflow sensor. The worst part was the fuel consumption shot up by nearly 30%—a full tank got me 100 kilometers less than usual. At night, the headlights would flicker, and the AC blew hot and cold intermittently. The mechanic said if such issues drag on, the ECU starts sending erratic commands, and even the catalytic converter could be ruined. Now, the moment any warning light pops up on the dash, I rush straight to the shop.
