Hoping someone can help me out here, I have been trying to solve an intermittant issue for over 6 months. 2002 Diesel 1kz engine, fly by wire,updated model with stability control and cruise control. NO EGR.
When Stopping (It never happens while moving) error code 19 or (P1123) pops up and the engine enters fail-safe/limp mode. I restart the engine and all is ok.
It is intermittant, I have bought myself a scanner and it always puts out the same code. I took it to the toyota agents for a full code diagnostic and they told me without any shadow of doubt that it is the acceleration position sensor, the quoted me over $1000 to change it as it only comes as a whole accelerator and they don't sell the actual sensor seperately. I have taken a good sensor out of another perfectly working prado and it is still doing the same thing. I would have wasted the $1000 at toyota. Googled fault code and it comes up as accelerator position sensor out of range? Vehicle has absolutely no other issues, fuel performance is good, starts and runs perfectly. Any Ideas???
I have attached a picture of the dash lights when it happens.
