Sounds like an intake air temperature sensor replacement would be a good place to start, then clear codes & see what happens.

How to change check engine light in dash

It requires you to remove the speedometer head from the vehicle in most cases. The bulbs are small and accessible from the rear of the head. That said, they rarely fail, so my suspicion is that this question is being asked so as to be able to remove the Check Engine light, either to remove the nuisance of seeing it or to attempt to hide its presence during a vehicle inspection. Most states that have vehicle inspection laws require the Check Engine light to work, and if it does not, the inspection is a failure from the outset. Inspection mechanics are trained to check for this by turning the ignition key to the ON position without starting the vehicle, a position referred to as "bulb check". Be aware that a properly trained inspector will know if you are trying to get away with something......

Check engine ligth still on

If the Check Engine light is "still" on it is because your engine control system "still" has a problem. These things do not go away by themselves. One must scan the Engine Control Module (ECM) for fault codes that will tell you which of the many SYSTEMS monitored by the computer is failing. Once the malfunctioning SYSTEM has been identified by the fault codes retrieved from the ECM, then the system must be properly diagnosed to determine the actual CAUSE of the failure. Only after the cause of the failure has been determined can the system be repaired so that the check engine light will stay off.

Plese note that fault codes only identify malfunctioning systems - they NEVER tell you what parts to replace.

I have a 2007 toyota corolla automatic.. I have had the check engine light on and cannot get it inspected with the light on i brought it too a garage and the transmission specialist said that that code...

Any code that puts on the check engine light is a failure for inspection. Your mechanic has given you bad information. What you need to do is fix the code causing problem then drive vehicle for a few days to reset all inspection monitors. You will not pass inspection with a check engine light on unfortunately. Hope this helps.

Service Engine Soon

With no noticeable change in performance, chances are that the problem is a failing oxygen sensor - which will affect pollution output and possibly cause your car to fail its next safety inspection, and the tach failure indicates a possible cam sensor failure. The only way to tell for certain though is to have the car's computer scanned. Your mechanic can do this (for a price), and many parts stores will run a limited scan at no cost (in the hope of selling you something).

Is the check engine light considered to be a sensor? My car failed smog due to sensor lights, do i have to go to a dealer to have the problem resolved, or can i do it myself

your car failed because they wont pass you until the light has been reset. the check engine light means the computer detected a fault in a sensor or system that may need"ll need access to a shop or someone who has an obdII diagostic reader and see what was might get lucky and can have the fault reset. If there is a true failure in the system the light will come back on again and repair will be needed. usually the code will tell you which component or sensor has failed. if you like you can purchase one of these devices from an Autoparts store for around $100..these more expensive models are preferred because they not only will reset the fault but will list the code and tell you exactly which sensor has failed... that is if your car has an obdII type system diagnostic connector; usually located under the drivers steering column.

Repair info on OSD Fault Code: PO743

The code is for a TCC (Torque Convertor Clutch) solenoid problem.

Chances are pretty good the problem is the wiring where it goes into the transmission or the TCC solenoid itself which is in the valve body

There was a bulliten released from Ford about three years ago about this code being set after trans overhauls. In Ford's program stratagies, the P07xx codes are for computer detected failures due to mechanical responses. The P17xx code series are computer identified electrical failures. This code you are getting gets set when the computer does not see the what it would expect from Torque Converter lock-up. The most common problem for this (and is even stated in the bulliten I mentioned) has to do with a seal on the input shaft of the trans. The seal either gets damaged when the torque converter is installed or it is accidentally left out during the rebuild. There is not much that you personally can do, but at least you can understand how to best procede.

you will most likely end up removing that cover to inspect the harness that goes to all the solenoids and then to inspect the valve body and the TCC solenoid itself. If you have a multimeter then you could ohm through the harness and even the solenoid. I have found that most of the time this code was produced because of the solenoid itself. But it could be the circuits to it also. There is a big connector an top of the trans that goes into the trans and the internal harness inspect that connector for any corrosion or damaged pins or wires.

TCC solenoid circuit failure during on-board diagnostic.

TCC solenoid circuit fails to provide voltage drop across solenoid. Circuit open or shorted or PCM drive failure during on-board diagnostic.

Failed ON - engine runs rough/vehicle shudder, engine stalls in DRIVE (2nd, 3rd or 4th) at low idle speeds. (Short circuit).
Failed OFF - torque converter clutch never engages (Open circuit) (MIL on).

Got Tune Up, but failed smog because Check Engine light is on.

I take it your talking about "check engine" light. Have you tried disconnecting battery for a minute or so? If light comes back on, try cycling your key just to "On", off, on, off, on & then leave in "On" position (not start) & count flashes of check engine light. Will be 2 digits, for example: 3 flashes, pause, 3 more will be code 33. 2 flashes, pause then 5 flashes would be code 25. Write them down & lets see what you get,and let us know. code 55 means end of message.
