Q: The check engine light goes on and off after the car gets warmed up. the analog temp gage is reading normal, there is no "smell of a hot condition" under the hood nor does the radiator give the hot condition or a cold condition as a malfunctioning thermostat would indicate. The cooling fan starts up when the analog temp gage shows its getting hot, appears to be normal. I have changed the auto trans fluid (spin on filter also, the magnet did not show unusual particles or was excessive)and the fluid did not smell burnt. According to the owners manual, it says that the check engine light comes on when the coolant or transmission is over temp, neither was the case, the dealer says "bring it in". Also the exhaust does not smell unusual and the catalytic converter area does not feel overheated. Gas mileage is good, power is good, air conditioning works good, heater works good, I'm at a loss. Why does the check engine light come on?
A: So if the sensor that signals the gauge or the gauge itself is defective, or the wiring to the control unit that moniters this and turns the fan on "see's" the incorrect signal... Ed
Q: Every thousand miles the engine's oil completely runs out of my SC2, such that the dip stick is completely dry.
There are no visible indications on the outside of the oil cap, or around the oil pan, what could be the possible problem, and what range of cost would be associated with fixing it?
A: Run your finger around the inside of the tail pipe and see if it is "sooty" and black..
If so, the engine is burning the oil.... if not, the engine is leaking the oil..... Ed
Im recieving a code 26 "quad driver output fault" from my Saturn.
Here's what it's doing....
When cold it will stall, die, and hesitate very badly. It seems like it does not want to go past 3500 rpms.
When warmed up, it doesn't die and revs fine but it seems to have lost some power.
I've tried to get information from a dealer technician, but he just told me he couldn't tell me what the quad drivers are, and for me to just bring the car in.
Now I'm not about to take my car to them if a tech there can't tell me what a part is on a car.
He knew what code 26 was but that's all he wanted to tell me.
Please help, if I knew what the quad driver was I'd replace it myself and be on my merry way.
p.s. if you know or when you find out could the symptoms my car is having be related to the quad driver? Thanks in advance..
A: Quad drivers are part of the computer system controls of your car and on your car I believe they "drive" the injector "on" time in milliseconds......
Yours are inside the computer and unless you want to be guessing (no return policy) with parts, or you have the equipment to check this, you may want to find a Tech you can trust....
Good luck with this......
