If it is a Tercel or MR2, it is T and E1 terminals. Code 21 is main oxygen sensor signal fault. Code 51 is A/C signal on; DL contact off (in transmission shifter with diagnostic connector jumped). I have no idea what that 51 means.

Engine check light on and when you run the vehicle, not enough power is driven from this car..

The engine check light comes on when the CPU has found sensors outside set parameters and sets the engine in limp mode to reduce the chances of serious damage. Run codes to find what has happened and replace faulty sensors. Check oil levels and water levels at the radiator cap. When all is repaired then you will have to use the code reader again to reset the engine light

How to reset a indicator light in toyota innova 2005 model?

Indicator light about what? Check Engine light? If the Check Engine Light illuminates constantly during driving with no noticeable driving or performance problems, there is a permanent fault in the emission control system. When this happens, the computer that controls the emission system usually has a backup program that runs while the fault is present. (These backup programs are often referred to as "limp home" mode programs.) You should get the vehicle serviced as soon as possible, but in most cases, the vehicle will continue to operate, though you run a risk of it dying or not starting.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Have you recently purchased the vehicle. A rebuilt agent with, racing seals & a racing oil pump, will run around 75 - 85 lbs pressure. If it just started happening on a vehicle you have had for a while, a defective guage. Or look for a plugged oil chamber, (near impossible without dis-assembly). Bad oil sending unit (part that sends the signal to the guage.

What will cause my Toyota Hilux to smoke with loud engine noise at high rpm? When accelerated to speeds of approimately 130km/hr, the engine races of, which feel like no control to the vehicle, smokes (...

If there is a blockage in the engine breather, that can cause this to happen and if not corrected, in a diesel, can cause runaway and it will destroy itself.

The check light is continously shown ON

Remove the terminal head from the battery if only you run a scan and there seem not to be any issue or code reported.

But I strongly recommend the scan.
