I am assuming that you have a series 80 diesel engine and that it has run for about 100,000 kms hence the warning light and the changing of the timing belt. Based on the instructions of its repair manual you need to "remove the grommet off from the speedometer and turn off the lamp by pushing the warning light reset switch, then replace the grommet." Alternately, you can try to reset the entire computer of the vehicle by removing the battery cables for a couple of minutes. Pls note that some car radios/head units would revert to security default (ask for a code) when power is completely removed.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

P0171 is a lean code. Open the hood, and locate the mass air flow sensor. Small black thingy in the intake tube between the air filter box and the engine, held in with 2 small screws. Remove the connector, remove the screws, and remove the sensor. Look into the sensor, you are going to see a couple of wires deep inside it. They will probabaly be "fuzzy" looking. Spray some brake cleaner on the wires until they are nice & clean. This will cure the P0171 code. Then check the air filter; replace it if it is dirty.
P1130 is an air-fuel sensor code, bank one, sensor one. More often than not, when we see this code, we replace the air-fuel sensor. Buy the replacement from you Toyota dealer, because the aftermarket sensors will not send the proper signal to the ECU, and you will be upset for having to buy a second sensor.
P0440 is a leak in the evaporative side of the fuel system; this looks after the fumes of the fuel in the tank. There are several reasons for seeing a P0440, like leaking vacuum lines, faulty fuel cap, rusty fuel filler tube at the cap, etc. This is kind of difficult to rectify without the proper equipment needed to diagnose what & where the actual leak is.
Hope this helps, please consider kind remarks regarding this solution. Thanks.
