Question about 2003 Pontiac Sunfire

3 Answers

2003 Sunfire Hello I own a 2003 Pontiac Sunfire. My car has over 90,000 miles and today on the highway, my "low trac" traction light came on and then my battery light came on. The car started to slow down (not matter how much I pushed on the gas) and the lights dimmed before my car completely shut down. The lights and the radio were still on but everytime I tried to start it, it would start but would cut off.

Try to recharge your battery if its starts now ,the alternator must be bad,if still wont start make sure battery is good,then check the fuses and fuseable links.

Need to change the altenator, this happened to me, or check the connections and make sure that they are not overly corroded. your alternator isnt pushing enough voltage back into the battery to charge it while you are driving.
for me after getting an alternator, the person that changed it for me said that the connections were really corroded and they weren't makeing a good enough connection.

Your computer has too many sensors for your car, and the computer shut down. You need to get a computer diagnostics done on your car to see if the computer is still good. That is gonna cost you about 65 bucks to do it.

I have a 2003 Pontiac sunfire and today while driving the check engine light started flashing and the trac off light came on. the car has a burning smell to it .got home and touched converter with paper...


with the check engine light flashing you have a code set in the pcm that you need to have checked out as the light will only flash if there is a problem that can cause damage to the motor,like a convertor problem or overfuelling problem.if the light came on and not flash there is a code but not a possible engine damaging problem.that is the difference.either way you need to have it checked at a shop by a tech.the trac off light will come on some cars if a certain code is set in the pcm to get the driver to have things checked out that could cause damage,its just the way the manufacture has set things up.this does not mean there isn`t a possible problem with the traction control system.

What dose trac off mean


It means your traction control system is off.
If you are on a wet road for example and your wheels starts to slip, what traction control does if it is on, is to electronically slow down your wheels until you regain traction on the road again.

Your Pontiac is equipped with traction control which prevents slipping on icy roads. TRAC OFF means the traction control is not engaged

ABS and TRAC lights are on


This could be and indicator that an abs sensor has gone bad or intermittently losing its signal. This may require replacement of a bearing hub asembly in which the abs sensor is incorporated into.The traction control uses the abs to control slipping when traction is limited. If the abs becomes disabled the traction control does as well.

Sounds like water in your distributor. I would replace you cap and might as well do your rotor while you are at it. Cheap and easy to do...

Trac off light comes on a 2003 pontiac grand am


This is the TCS or Traction Control System. It helps keep the vehicle from being able to get stuck by forcing the torque to either tire. Usually there is a switch either on the dash or on the shifter that says TCS or TRAC press the switch and it should go off.
