    ( 1 ) No Idea unless it can only store 2 codes at a time. ?? Try putting some false codes in and see if it only logs 2. ??


    ( 2 ) Yes. A faulty Lambda sensor heater circuit will log a fault code on a Toyota and put the Mil light on within a few seconds of Starting.

    We have Funnily enough just had one in with a simlar fault, poor starting, Wouldn't rev properly, and logging Cam Sensor fault. ( Wouldn't alway's start )

    Ours had a faulty Crank sensor but the Cam sensor was fine, ( No signal on scope from Crank sensor.) And The Timing was out by 4 Teeth although the Chain was tight and no one was supposed to have Touched it. ( But it had come from another garage, so we don't know if they had been playing. )
