Thank you for a reply.
Here in Belize nothing comes easy. The Toyota dealer is 80 miles away and is as corrupt as most businesses here.
Lying is as normal as breathing.
Making duplicate keys and selling them so vehicles can be stolen was on the news not so long ago.
A few months ago I had the codes read and nothing showed up. But that does not mean there was no code.
They may simply not be interested to fix it. So they charge $50.00 to scan and send you away.Can you tell me which sensor could be the problem and where it is located?
The sensor may be cheaper to replace then another scan.
Is the actuator external and removable or is it internal and requires the removal of the entire transmission and transfer case?
Is the actuator electric or does it work by vacuum?
When I press the 4WD button a small plastic solenoid valve opens under the hood on the fire wall and engine
vacuum sucks air in through a little filter on top of the solenoid. What is that for?I have checked to see if the 4WD is locked up all the time by raising one side of the vehicle and turning a wheel by hand.
With engine off and transmission engaged, front one turns forward the back turns backwards. Seems normal to me.
With engine on and the transmission in neutral, they turn freely by hand, whether the 4WD button is pressed on or off.
With engine on and in gear, both front and rear turn and I can stop either front or rear and the other speeds up.
So I think the actuator does not work.
I don't really care much about that, but would like to know what makes the beeper go off.
How can I shut it off??? What else sets the beeper off?
Does the computer reading the temperature sensor for the cooling fan, affect the engine settings when 4WD is engaged?
