SOURCE: Re wiring

Thanks for your concern guy's. We did manage to fix the problem....It took us about four days of laborious work....We had to remove the harness covers and work our way backwards and forward, from the management computer, to and from the relevant 'sender unit' coolant temp, air temp, manifold pressure, lumda and oxogen sensor and from the controlled units, ie, ignition system, injection system, cooling fan set up and so on. We managed to identify the connections by following the identification labels printed onto the circuit boards.

We think that Toyota could make life a lot easier, if they used a standard wire colour coding and did not change that colour inside the loom....It is not un-common to see, as an example, a red with white tracer at one end and that may be joined to a blue with red tracer at the other end....If the loom cover is not removed and the cable inspected, you could not guess from what goes in, what will be coming out.

Hope this will be of help to someone somewhere.

Best regards

SOURCE: I have toyota Gaia wit 1az-fse engine when engine check light comes on it loses accelleration power,so we changed the fuel pressure sensor nothin changed next we changed computer bt after some time th

In stead of changing what is not wrong, save money and time by having the fault codes read and fixing the fault
check engine lights refer to both an engine problem and a transmission problem so what you may have could be in the transmission.

SOURCE: Toyota Noah 1az-fse motor. I was driving and it cut out. I then diagnosed the vehicle and it came up with throttle/pedal sensors a circuit and inlet manifold barometric pressure sensor circuit.

have they tried clearing the faults an re calibrate the throttle body
if that's been done replace the sensor
for now wouldn't worry to much about the manifold sensor cause that can be because of the throttle fault

2001Toyota Rav4L 1AZ FSE won't start test crank and cam sensor good high pressure pump good no pulse from the injecter wire using pulse light could you tell what's wrong.


No pulse means computer is not getting something it wants. Do you have spark at plugs? Correct fuel pressure? Security system needs reset?
