my vtec dont work

My car was crash and after the repair my vtec stop work and my check enging
light stays on and when i used the ODB11 scan tool to cancel it the light
come back on in lest than a second . The code is coolant temperature
switch low imput. The car is a honda accord 1997 and the engine is a F28B
it`s from japan

 

Rather than just cancelling the code, why don't you tell us what the code
number is? It might help you figure out what's wrong.

 

---------------------------------------------

Vtec won't work if it can't tell that the engine is up to operating
temperature. Have you tried topping up the rad and filling the coolant
reservoir to the MAX so the coolant sensor will be properly immersed
when the thermostat opens?

What was the displayed CODE (numeric, not interpretation) ??

'Curly'

 

how do i retrieve the code number without using the OBD11 scan tool

 

umm.. in your fisrt post you said "when i used the ODB11 scan tool " so, use
it again (or go to autozone or some autoparts store, they read it for free.
just make sure you get the code number). the whole point of the check engine
light is to tell you a code is stor, and that code tells you whats wrong.
it's not just an "idiot light"

 

the code am getting is P0117

 

Engine coolant temperature, low input.

 

What does that mean. What do i do now change the switch or how do i check
it.

 

Since you are NOT a mechanic, you should consider taking your car to a
mechanic and having him or her check the condition of the cooling system.
You failed to include the former posts related to your problem.
I believe that the following trouble code was displayed:
P0117 Engine coolant terperature circuit, low input

What steps have you taken to make sure the cooling system is in working order?

Is the radiator filled to the rim? (Don't remove the cap unless the engine
is cold).

Are there any leaks related to the radiator, all hoses, etc.

If you plan to do the work yourself, visit a auto store such as NAPA
and purchase a repair manual for your vehicle and read the sections
related to the cooling system.

I bet the sensor is in the radiator or somewhere else where it was
damaged in the crash. Either that or it wasn't reconnected after the
repair or they damaged the sensor or wire during the repair. If you
can find the sensor, a visual inspection and wiggling any connectors
may be sufficient to identify or solve the problem.

 

also cheap and easy to find where the various plugs are, and reseat the
connectors. might have a touch of corrosion on em.

 

Just out of interest, where are you plugging the OBD II scanner into?
