pontiac grand am se 98

15 years ago

I have a Pontiac grand an 6 cylinder 2.4 engine. I have a abs light showing a low trac and to the right there's a red arrow facing down light showing. Can y'all explain these warning lights that appear and what they mean?

The abs and low trac lights are likely related. ABS is the anti-lock brakes, and TCS is the traction control system which needs the anti-lock brake module to function correctly. The TCS lamp will come on with just about anything that sets a trouble code in not only the ABS but also many of the fuel injection system hard faults will cause it too. The TCS operates by the computer first quickly detuning the engine when it senses one of the front wheels spinning, which it detects through the ABS wheel speed sensors. Then if necessary the ABS actually starts pulse locking the brake on the wheel that is spinning, and that causes power to transfer to the other wheel, increasing grip, and reducing wheel spin. I suspect you have an ABS system issue that will need diagnosed.

The red arrow down lamp is a good question, I can't think of what that might be off hand. First suggestion is to check the owners manual and see what they are using that for, but of course somehow I expect your gonna say the car didn't come with the owners manual. I'm away from the shop so I can't even check my information system to see if its listed, but really I would not expect it to be, or at least it will be difficult to search for it by what the light looks like.

By any chance has the battery been replaced or disconnected lately? My son's 03 Galant had the exact same issue after the battery was replaced. It drove us crazy trying to figure out how to get the computer to relearn the idle. Until we read the owners manual about replacing the battery, that said to let it idle for 10 minutes after reaching operating temp. It worked. This might not be your issue. But I thought I'd use your post to bring to light what can happen when the battery is disconnected. Good luck with it.

That may be normal. Just how high is it? In cold weather, it might go to 1200 rpm at first start and then pull back to 900 rpm in the next few seconds. After a few minutes, it should settle to about 700 rpm. If the engine hits 2000 rpm on startup and is too slow in reducing speed, it needs attention. This assumes it was started with your foot off the accelerator and allowing the engine controller to control the process. Also, you may note this happening in cold weather: The idle speed increases slightly when the gear selector is moved from park or neutral to any gear. What's happening is this (for automatic transmissions): When the transmission is put into gear from neutral, the engine controller increases the idle speed a bit to compensate for the extra drag put on by the transmission. If the transmission is a little slow in engaging, the engine will speed up and then drop back in rpm as the transmission cluthes fully engage. This effect is less noticable after the transmission fluid warms and the shift from neutral to a gear quickens. The effect is more noticeable with transmissions that have accumulated wear on shifting valve seals and clutch facings.

If you have an automatic transmission, you may be experiencing problems with the lock-up clutch. A sensor controls the voltage to the lock-up clutch and this is a common failure with GM lock-up clutches. The fix is simple - replace the sensor. To diagnose, temporarily disable the clutch by unpluging the lead to it. If this is the problem, it disappears when unpluged and re-appears when reconnected. The sensor is failing. Within the range of 45 to 55 mph, the lockup feature may be disengaging and engaging when the throttle position is suddently changed by a significant amount and will cause a small lurch. This is normal, however, lurching increases when the torque control part of the engine mount is worn. It may need replacing.

If it is the waterpump I'd expect that you'd either smell antifreeze or see it dripping. The light should go off as soon as the coolant level is correct. For now, ignore the light--just add coolant to the full mark, and then keep an eye on it. If it doesn't drop and the light continues to stay on, the low coolant sensor is probably bad. If it does drop, you probably have a leak--I'd suggest taking it to a service station and having them pressure-test it. (I think you can also go to Autozone and rent a pressure testing kit--it's pretty easy to use).
