Slow down, don't start tearing down the engine just yet. Error 74 is: P0074 Ambient Air Temperature Sensor Circuit Intermittent.

SOURCE: 1994 toyota pickup idling problems

Could be a throttle position sensor going bad or a loose or leaking vacumm line or loose or worn wiring harness. You had mentioned the engine starts heating up. Do you mean overheating or operating above normal temperature? Sounds like a vacumm issue with the fluctuating idle. Check for worn vacumm lines and check to see if the vacumm is functioning. Sometimes a simple vacumm line with a loose connection or a small hole in it can affect your idle. Old lines are easily replaceable and an inexpensive place to start, then try your egr valve, pcv valve, brake booster vacumm line, oxygen sensor could be worn and affecting the mapping of fuel and air on the computer. Usually the check engine light will come on in this case.

SOURCE: Where can find a fuse panel diagram for a 1986

You should be able to find a fuse panel diagram in the back of any repair manual(Haynes) which you can get at any auto parts store. The fuse panel in the glove box is for your fan and air conditioning. The other fuse panels are general. Your truck should be a 22r carborated motor unless altered.

Not sure if the fuses are in the right place and running lights do not work on '88 toyota pickup


Hi there,
You'll find one fuse box under the bonnet (hood) and another next set on the kick panel inside the cabin....The running lights (Park / marker light also operate the instrument panel lights....The covers of both boxes have directories inside....The one you're interested in is the one inside the cabin....

Engine light on Codes show 1. Po 441 evaporation emission system incorrect purge flow 2. Po442 evap emission system leak (small) 2. 446 evap emission system incorrect purse flow 2004 Toyota Tacoma pickup...


Hello! Those three codes commonly indicate the followi possibilities:

The gas cap was not sufficiently tightenend ater fueling, a bad gas-cap rubber o-ring, the vehicle had the key in the 'on', or engine running, or the tank was filed all of the way up the neck.

Any one of the abope causes will set all three codes.

81 toyota pick-up. No spark


Check to make sure the main fuse is good. Sometimes those blow when you short out a wire from the battery to the ground on the car *like when an alternators live wire hits ground on the car.
On a 1981 Toyota pickup, im unsure of where it is located, but sometimes they are located in the fuse box, as a big fuse usually a 100 amp or 80amp fuse.. Sometimes they are located along a ground connected to the engine and the frame of the car. This could make it just crank and not start.
Check also to make sure that the engine is grounded, by taking a test light and connecting it to the positive side of the battery, and testing the metal around the motor. Sometimes grounds can break, or when shorted out they can melt. If the motor is not grounded then it will not start. and will just crank.
Hope this helps a little - Jarett

Upgrading 4 to 6 cyclinders in '81 Toyota 4WD pickup?


yes it is possible, but very involved. Personally I would buy a donor Toyota pickup that has a V6 in it. U-hual had a lot of those. It was the really small box truck.

You will need everything basically, the harness, the computer, and anything specific to that engine. Would make it a whole lot easier if you had the donor truck right there.

Oh, and by the way, it is a very tight fit.
