really all you have to do is to take the car to autozone and have the fault codes read for free. This will tell you what sensors are faulty. Take the car to an accredited service centre that specialises in your car and have the problem sensorsfixed.

Nze121 engine making rattling sound


run fault codes and look for knock detector sensor faults. The rattling sound is probably detonation from incorrect air /fuel mixture ratio and the sensors are there to tell the CPU so that the timing and fuel mixture can be adjusted to stop it as it is detrimental to the engine.

2005 Toyota Corolla check engine light on.Fault code P2716,undefined reading.What does this mean?


Hi
Could mean there is one fault causing many faults, example, Air mass sensor, this can cause rough idle and over fuelling so the code reader will just send it back with undefined as there are to many faults to identify as the cause.

Most likely it will be a air fault so check the air sensor first, try cleaning it with carb cleaner, sometimes works. If not get back to me could be 2 other things. although the car will not drive very well if it is any of the other 2.

Regards
Dan

Toyota corolla 2008 engine light


i think your right about the dealer, the code reader will tell the mechanic what is sending the fault, for him to change the air flow meter then the wiring is bizzare as these are 2 major seperate items and the codes would tell him that. My suggestion, take it to a local mechanic who has a code reader to tell you what the fault is, most mechanics won't charge to have a look. Toyotas are usually a pretty reliable car. Hope this helps, Good luck
