Sensors In Cars

Before your car actually starts, what do you see ? Usually, a Christmas tree of lights on the dashboard. One by one, these lights go out; as sensors communicate with computers.

Once started, the other sensors report their status to the driver. Commonly, through a general “systems OK” message. Consequently, Some cars alert the driver only; when there is something wrong.

Analog Sensors

So, In the old days; sensors and were very simple. There was an oil light; that would come on; when the oil pressure was low. There was an alternator light; that would come on; when the battery; was not charging.

Digital Sensors

Today’s vehicles; are obviously more complicated. As a result, Digital computers now control engines. Luxury cars have “body computers” to control luxury features. And, all of these computers; rely on sensors in cars.

Car engine sensors; continually monitor major systems; sending real time signals; to onboard computers. And, these computers keep track of everything. Consequently, alerting the driver; only when something is wrong.

Troubleshooting Sensors In Cars

So, A failure of the crankshaft position sensor; has no way of figuring out; when the spark plugs should fire; so it won’t start. Similarly; if the temperature sensor should malfunction; the computer might attempt to compensate; for what it has sensed as; a cold running engine. It might adjust the fuel injection and timing. Also, causing the engine to run poorly.

So, The missing or stuttering engine; would lead a trained technician; to assume that there is something wrong; with the ignition system or the spark plugs. In reality; there may be nothing wrong with the engine. And, it may be operating at its proper temperature. But, because the sensor; has told the computer that there is a problem; the computer sets out to correct it.

Sensors In Cars Conclusion

Finally, It has become very difficult; to diagnose a vehicle problem; without sophisticated scanning computers.
