My girlfriend has a 1997 Ford Taurus, 80K miles. Since buying it slightly used in 1998, she has paid several hundred dollars per year to make the SERVICE ENGINE SOON light (aka the PAY MECHANIC NOW light) go away, which lights up at least once or twice a year. Rarely has the car exhibited tangible symptoms of a problem-i.e., dying on the road, unusual sounds or behavior, etc. But it sure seems think it's sick a lot.
Unfortunately, Arizona MVD no longer cares about the actual emissions from a vehicle; they care about lights. If your SERVICE ENGINE SOON light is on, you fail, regardless of whether the reason has to do with emissions. (Perhaps all states have the same rule now.) Therefore, she's had to pay whatever price necessary to make the light go away in order to get her yearly tags.
The latest problem seems to be threefold: bad gas gage sensor, bad throttle position sensor, and bad "accident" sensor. Repair cost will be $500. (As for the gas sensor, my girlfriend indeed said her gas gage wasn't working properly. I don't know about the TPS other than that her car has been driving fine. The "accident" sensor is allegedly something that'll shut down the car if it gets in an accident. Anyone know about this? I don't have too many details, as I didn't talk to the mechanic personally.)
Now, as in the past, the problems are usually attributed to sensors. So, does this mean that problems are usually electronic rather than mechanical? When a sensor senses a problem it could just mean that the sensor itself is malfunctioning, right? (Hope my questions make sense.)
I'm wondering whether all these problems are the symptoms rather than the cause. Could an electrical short just be causing various sensors to fail quite often? If so, is the OBD2 diagnostic not sophisticated enough to see the cause behind the symptom?
I understand that cars age and you must pour money into them. However, my
1996 Saturn station wagon has had twice the miles and half the problems of my girlfriend's 1997 Taurus. She really wants to dump the thing. Are Tauruses of that generation just lemons?Ethan
