My 2000 eclipse gt is getting horrible gas mileage, took it to o'reillys to hook up a code reader and we got a p1400 code. he explained to me what it is. but no idea where it is on the car or how it could effect my gas mileage.

Type: 2000 Mitsubishi OBD P1400

There is a lot for you to read

Then have a repair shop properly test the vehicle
& make the repairs

The free code read at the parts store is a waste of your time

If you want buy a cheap code reader at auto zone, but understand why you have it & study OBD2 Systems & it will only read Generic Codes & a few others,always need professional software to look at data,road test with it & more

Codes usually have nothing to do with the need to install parts

You can have codes stored,lots of them & no check light on
your dash,you can have problems & no codes, but need the scan tool & other reference material & test euipment

Get your VIN and go to a dealership. If you ask real nice they will probably give you the code to unlock your radio for free.

SOURCE: 2000 eclipse gt getting a po1400 code and car does

PO1400 is not a common code. PO140 however is. PO140 is a oxygen sensor problem, it refers to bank 1 sensor 2 having no activity. This could cause your eclipse to not hold a good idle and possibly to stall. I would have a different mechanic check the car before you spend quite a bit of cash on an ECM as they can cost upwards of 800 dollars

I'm having the exact same codes on my '01 GT. http://www.club3g.com/forum/problem-reports/112664-p0403-exhaust-gas-recirculation-circuit-malfunction.html

check out the last post on that page. literally just got done getting the "BB" out of the tubing. haven't found out if it solved that problem yet, but I'm hoping to not have to change the solenoid.

I'm still working on the P0128

Check engine light on but runs fine

the light comes on for 4 reasons.
1: SMOG. failing.
2: horrible MPG. (engine is running in limphome mode....... fix it.
3: pending doom. (early warning)
4: the NAG lamp , the old leaded gas, mileage nag light (USE FED only model)
there is no need for any reader ( they dont sell them for trackers, and sidekicks)

all there is , is the paper clip test. the winky-blinky test.

Security system on 2000 eclispe GT

Use the KEY (not the REMOTE) to UNlock the driver's door or the trunk. Then use the key to START the car, then shut it off. Finally, get out and LOCK the car using the mechanical KEY. That should clear the security system codes caused by disconnecting the battery!

Service engine light on 2000 mitsubishi eciplse GT V-6

This could be as simple as a loose or defective gas cap. Beyond that you will need to retreve the codes with an O.D.B. II code reader.

Buick regal 92 3.8L Horrible fuel mileage

Sounds like you might have an oxygen sensor problem. Your catalytic converter(s) maybe defective or dirty. That in turn can dirty up the oxygen sensor. A defective oxygen sensor will send faulty info to the computer, interpreting the fumes as cold (even when the engine warms up). That causes the computer to adjust the fuel mixture to very rich, giving you poor gas mileage and the fuel smell. Hope it helps.
