I used to get this same code. the trick is not the egr valve. the small channel leading from the egr valve into the air intake manifold is what needs attention. that channel or tunnel is probably clogged with exhaust residue. you have to find a way to clean that out with elbow grease. no solvent that i have found will do it as well as a coat hanger twisted into a 't' shape. once that is cleared out, you should be good to go. good luck

How to I get the, "low coolant", light to turn off on my 2001 Chevy lumina


have the coolant sensor checked and check the wire to it
they work by having a continuous power supply through the sensor through the coolant to earth to keep the light off
any break in that wire of sensor results as a low coolant because the power can no longer earth out and so the light comes on

Why is my1997 chevy lumina low coolant light is on and the radiator is full of coolant ?


In most newer chevys, the coolant reservoir is part of the pressurized system. Rather than just holding overflow coolant and relying on the radiator pressure cap to draw from and expel to the reservoir, it is an active part of the cooling system. On these systems, there is a coolant level switch in the reservoir. This will activate if the level in the reservoir gets below a certain point. So it is possible to have a full radiator and still get a low coolant light. Be advised that as the reservoir ages and get stained, it is not uncommon for the low coolant sensor to give false indications of low coolant.

Why is the low coolant light flashing?


The low coolant light is operated by a level sensor located in the coolant reservoir itself. If the low coolant light is on and the coolant level is full then wither the sensor is unplugged or the sensor is bad.

The fact that the oil was low would not be from the oil pump, but from wear in the engine. If it is not smoking when you start it or as you drive, you can probably keep it running by just keeping the oil level checked at each fuel fill-up. As for the car shutting off, you didn't say if the engine seized or got real hot. A low oil pressure problem should have triggered a warning light before the problem got to the point where you lost the engine.

If the car ran after you added the oil, you got lucky and need to always check it.

'low coolant light' flashes all the time and then 'service engine soon'


These problems may or may not be related. The Check coolant light means that the coolant level in your radiator is low. If you have checked it and it is not low, then the sensor is most likely defective. The low coolant sensor will not turn the Check Engine light on - even if the coolant really is low. There are many things that can cause the Check Engine light to come on. You will have to scan your Engine Computer to find out why it has been turning the light on.

I did have a problem on one of these cars one time where the Check Engine light was coming on and there were several codes for the Throttle Position Sensor(TPS) and the Manifold Absolute Pressure (MAP) sensor and the car ran really bad. The Check Coolant light was also on. After checking it out I found that the coolant level sensor was shorting out the 5 volt reference circuit (VREF) from the computer and causing the whole problem. Replacing the coolant level sensor fixed the car.

More than likely the coolant level sensor(float) is corroded or stuck so it's reading low. If it's not overheating and heater is still blowing warm air, you can probably still drive it safely but keep an eye in temp CLOSELY! Something you might consider, is having your oil change done sooner than waiting for next 700 miles and have them flush your cooling system at same time - just for peace of mind,

Two things; 1) check the coolant level of the coolant overflow. Sometimes when the coolant level is low it will trigger the check engine light to come on. 2) If the car is running hot or high check the thermostat. These are the least expensive ways to go, before any costly repairs.

Low coolant light is on but does not overheat and has plenty of coolant in radiator and reservoir


Those sensors are bad all the time. It is the sensor on the radiator tank. They have fingers on them that trap air bubbles. You can try tapping on it, but that usually breaks it anyways. The fix is to change the coolant level sensor.

Anyways if that helps you any little bit, then feel free to follow me on Twitter. That one is at: twitter.com/acoates23234

Thanks for the vote, and good luck!

Low coolant light is on but does not overheat and


There is a low coolant sensor down alongside the radiator. Either the wire came off or the sensor has failed. Other than the annoyance of the light being on if you keep an eye on the coolant level it will cause no harm.
