What does the code p0125 on the ECM mean?
The ECM monitors engine coolant temperature through a sensor after start-up. If no information is coming from the sensor after the engine is warmed up, this will trigger the code P0125. Possible causes include low coolant, stuck or bad thermostat, or faulty sensor.
What does a bad MAF code mean on a Toyota?
The most common causes are a dirty air filter, dirty MAF or air filter housing, or faulty MAF. This code usually indicates a dirty or faulty mass air flow (MAF) sensor, or a vacuum leak downstream of the MAF sensor (perhaps in the PCV line or in the valve itself). This code can also signify a bad O2 sensor in bank 1.
