99 ECLIPSE SYSTEM ERROR
 

I BOUGHT A OBD2 CAR READER AND 3CODES CAME UP P0171,P1390,P1494.P0171 MEANS SYSTEM TOO LEAN HOW DO I FIX THIS PROBLEM WITH OUT TAKING IT TO A SHOP TO HAVE REPAIRS DONE.

RE: 99 ECLIPSE SYSTEM ERROR
 

either your gettin to much air or to much gas. Do you have aftermarket intake? Or any fuel mods. Another thing that causes that is your O2 sensors. You should have an upstream and a downstream. Check both of them out to see if they are defected. ( they are in your exhaust pipe.)

I JUST PUT PLUG WIRES IN AND IT GOT RID OF ERRORS P0171, P1494. NOW I NEED TO KNOW WHAT A G-SENSOR INTERMITTENT LOW VOLTAGE ERROR MEANS AND HOW DO I FIX THE PROBLEM. PS. THANKS FOR THE TIME IN ANSWERING MY LAST QUESTIONS THE PLUG WIRES FIXED 2 CODES.

RE: 99 ECLIPSE SYSTEM ERROR
 

o2 sensors maybe bad...do a tune up

RE: 99 ECLIPSE SYSTEM ERROR
 

please shut off caps lock too lol.


as for therunning lean that means it is getting more air and not as much fuel. rich means to much fuel and not enough air I guess that is the easy way to describe it.

I still say do a full tune up on the car.

P0171- is a lean code from your first O2(bank 1)
Mostly caused by a intake or exhaust

P1390- is the G-Sensor Intermittent Low Voltage, I believe that has to do with your ABS
I think one of you wheel sensors, not sure which wheel

P1494- I belive is a emmissions code
This is a hard one just because I really don't know what exact emmission it is

You might have to bring it to a dealer or a mechanic to really check it out, theres only so much I can do online....but good luck.

RE: 99 ECLIPSE SYSTEM ERROR
 

how do i check the wheel sensors and where are they located. thanks for all the wisdom.

RE: 99 ECLIPSE SYSTEM ERROR
 

where r the 02 sensors located and can they be cleaned or do i have to replace them.

RE: 99 ECLIPSE SYSTEM ERROR
 

You should have an upstream and a downstream. Check both of them out to see if they are defected. ( they are in your exhaust pipe.) And you can not clean O2 sensors. You have to get new ones. It's not hard to do that at all. Look at your exhuast. You'll see something sticking out of a hole. It'll have 2 wires on it... Thats your O2.

I think if it was an ABS sensor then his ABS light would come on right? Unless it is on and he didn't tell us that, haha

I just did a quick search online for the code and it came up as "wheel speed sensor -1"
