Question about Toyota Cars & Trucks
When vehicle is running, engine check light is come out. At that time, we cannot race up engine.Therefore, I check diagnosis by jump wire on E1 and TC1. I received trouble code is 51. I don't know, it is sure for O2 Sensor problem. That vehicle have no TE1 and T1.
If it is a Tercel or MR2, it is T and E1 terminals. Code 21 is main oxygen sensor signal fault. Code 51 is A/C signal on; DL contact off (in transmission shifter with diagnostic connector jumped). I have no idea what that 51 means.
