What are the symptoms of a damaged car intake pressure sensor?
2 Answers
When a car's intake pressure sensor is damaged, the following symptoms may occur: 1. The engine control unit's fuel injection function may malfunction; 2. The engine may run abnormally or have poor acceleration; 3. Black smoke may emit from the exhaust pipe during engine operation; 4. The engine may fail to start; 5. The engine may experience poor acceleration; 6. The engine may intermittently stall. The causes of damage to the car intake pressure sensor include: 1. Open or short circuits in the sensor's internal wiring; 2. Blockage or leakage in the vacuum hose between the sensor and the intake manifold. The intake pressure sensor is a device that can sense pressure signals and convert them into usable output electrical signals according to a specific pattern.
When the car's intake pressure sensor fails, the vehicle becomes particularly difficult to drive. I've experienced it once myself—the engine would constantly shudder at idle, like it was shivering, with RPMs fluctuating erratically. Acceleration feels sluggish, as if stepping on cotton, with painfully slow pickup, and it might even stall for no reason, making traffic lights especially awkward. Fuel consumption noticeably increases; a full tank that used to last 500 kilometers might now only get you 400. The engine warning light on the dashboard stays lit, signaling an issue—best not to ignore it to avoid damaging expensive components like spark plugs or the catalytic converter. This sensor measures intake pressure, helping the car adjust the air-fuel ratio. When it malfunctions, everything goes haywire. Getting it repaired promptly is the best move; otherwise, the problem worsens, and repair costs climb even higher.
