Thats so easy.
You should do this:
1_check fuel pump pressure and injectors
2_check fuel filter
3_check distributor and spark plug
4_oxygen sensor and wiring
5_catalist
6_Fuel regulator pipe
After do all item, you should clear error code with:
On diagnostic port (under fuse box) jump te1 with TC,turn switch on,press accelerator pedal 5 and hold until check engine go to lighting.
So error code is clear.
If you need anything just message me on telegram or whats up messenger.my phone number is +989395094590.
Good luck
I always have this problem.
Just I replace fuel filter and fuel pump
You're going to need a new mixer, and maybe more and then if you're in Canada you should have a filter available for the lp hose so you can avoid this from happening.your mixer is contaminated and bad I have 1 available if you need it however you may need new o2 sensors as well that code is a mystery right now
Thank you for the information.
Lots of possibilities...1 connector contact defect
2 intake system defect 3 exhaust system defect 4 sensor defect 5 ignition defect 6 fuel system defect 7 harness defect 8 engine controller defect
Good luck...I would swap from a know good truck..if not available then start cheap with ignition switch...Then call a Toyota tech in your area..look for burnt or loose wire...and try reconnecting all harness connections checking for loose or unseated pins
thanks for your reply, I tried disconnecting the negative terminal but the code came back immediately.i tried doing the driveability test- depressing the gas pedal for 5 mins. then let idle for 2 mins. and then repeat this three times. During this test 01-4 came up and now i have both codes coming up.
First try disconnecting negative from battery for 30 seconds...if that doesn't clear it...go to the engine module plug with grey cover just below battery and jump out...I'll get back to you try the ground thing first
