How is the self diagnostics Code read on a Toyota?
That’s actually the very codes that we need to use!

When does accumulation of codes occur in Toyota?
Accumulation of codes in this mode occurs when the contacts “E1” and “Te2” are closed before switching on the ignition. After that, the car should drive about 15 km. After stopping the engine does not muffle and at idle the contacts E1-Te1 are connected and codes are read out.
Why does my Toyota engine have a code p0401?
When code P0401 is triggered, it’s because the DPFE sensor found too little recirculation. This code indicates that too much exhaust gas recirculation (EGR) is occurring — the result is an overly-rich mix of oxygen in the air/fuel ratio and higher engine temps.
How do you read the OBD code on a Toyota?
Use a copper wire or paper clip to short terminals TE1 and E1. Go back inside the car and count the number of flashes for the check engine light. This procedure will not work on Toyota vehicles equipped with OBD-II. For most 2000 and newer vehicles, you will need a code reader to read check engine fault codes.
