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
