2007 Mitsubishi Galant TCL Off light and service engine soon light

My TCL off light has come on many times in the past but not caused too many problems before now. Also when it is cold out the car feels like it is misfiring some but goes away after driving a while. However, this time i was driving down the road when both the TCL off light and the service engine soon light came on and my car is misfiring. I didn't do anything? I wondered if any had an idea of what this might be so i can have an idea of how much its going to cost me!

TCL is controlled by ABS system,could have an abs sensor going bad. There is alot of things that could cause a misfire,mass air flow sensor could be dirty or need replaced.Best bet is to take to someone with computer that can read what all sensors are doing in vehicle.

SOURCE: service engine soon.

it mearns that the computer is sensing a failure. You will need to see if it has logged any codes, and troubleshoot from there. You can go to many auto parts suppliers (autozone, ect) and many will read the codes for you, or you can purchase code reader and do it yourself

SOURCE: tcl & service engine soon

only way to retrieve trouble codes is by using a scaning tool. after reading the codes you can work in the sistem that fails.

Try replacing the fuse for the backup lights. Mitsubishi Galants have had this problem happen a lot as well. Don't know why it blows, or why the backup lights also are used for the same circuit, but that should fix your problem.

My tcl off light has come on along with my engine light and the engine has a missfire when on boost?legnum vr4

The "TCL" light has to do with Traction Control (part of the ABS system) the TCL light and the Engine light could be on for the same issue or there are two different problems going on. There is no way to tell unless you own a "Code Reader". This tool will have to be able to view both engine and ABS codes. There are several different Scan-Tools on the market. Mine is from Snap-on tools (Modis). But unless you run a repair shop, this isn't practical. Take your time and look around. Beware of buying a used unit. You may decide that it would be cheaper to just have a shop diagnose it. I'm not sure who you have for local part stores but you could call a few and see if they offer free engine code reading. Their tool isn't as advanced but if their tool will access engine and ABS codes. then they can give you a list of codes that were stored inside the ECU. It would be best that while you have the codes read. That both lights are on. Sometimes the light has to be on in order for the codes to be read. You can then write back with the list of codes. And I can give you a answers to what they mean, possible causes, and parts to check. I hope that helps, good luck.

Intermittant starts running crappy and tcl light comes on

When the TCL light is on usually means there's a problem with the traction control, need to have inspected real soon. Could be a speed sensor.

Engin light and TCL light won't switch off. When

TCL means Traction Control, and you turn it on and off with a switch. But you did not tell us make, model, or year, so we can't tell you how to turn it off or on.

What does the tcl dash light on a 2002 mitsubishi gallant ls mean

tcl is traction control. Google eclipse tcl and you will find your answer. Sounds like it is a common problem with the MAP sensor when people put on aftermarket air intakes.

TCL and Anti Lock brake light come on when sitting over night and when I drive it for a short distance the and shut the engine off and restart most of the time they stay off.This has been happening ever...

Interesting problem, especially since its been happening since the car was new. Researching this I found one suggestion that a front wheel bearing is in backwards, and this causes the ABS wheel sensor to read incorrectly until the TCL/ABS computers calibrate themselves.

This is an odd suggestion, as the wheel bearing and hub are an integral assembly. A part photo shows a "normal" looking bearing that only fits one way. A bearing installation problem is not impossible however. There could be dirt/road debris on the sensor, the sensor could be slightly misplaced, or faulty. The TCL/ABS computers read the signals from the wheel sensors, and has diagnostic outputs, which should include indications of poor or missing data streams from all four wheel sensors.

This is the first step to finding a solution. If the TCL/ABS computers are reporting errors from one wheel, then that wheel has to be disassembled to see what's the cause.

Lean bank one on my toyoata corrolla code scan

I would try replacing the spark plugs. The lean code can be caused by an ignition miss as the oxygen isn't used up completely in a misfiring cylinder.
