I went to check the check engine problem but the mechanic tells me that the error signal 52 knock sensor but my car is year 2001 he had a motor 4a but very likely change for 5a with a collision. Apparently does not have the sensor on this engine since there is so I can do ?. Also see this product according
http://foro.club-toyota.com.ar/viewtopic.php?f=22&t=1073
This error code is for vehicles with lower year 1996 and mine is 2001, which believes that the mechanic did wrong Did they done wrong? as I can solve?
thanks for everything.

The engine control unit is for an engine using a knock sensor and since the replacement engine does not have one, it would throw the code. Unless you install a knock sensor if not, you would not be able to clear the code.

I recently purchased a set of Halo spark plugs (said to improve mpg by about 10%), and discovered afterwords on their warenty that the timing will need to be adjusted. It sounds as though a motor management system or knock sensor (are those two different things, or the same thing with two names) will adjust the timing automagically as long as I disconect the battery before instalation. Does my car have a motor management system or a knock sensor? If not, how easy is it to get the timing adjusted? Thanks

Timing is controlled by the PCM (Power train Control Module). The knock sensor retards timing when it detects pre-ignition.

What they are saying, I think, is that if you disconnect the battery the PCM will re-learn engine parameters (timing/fuel) based on feedback from the engine sensors.

Unless equipped with a distributor, base timing in not adjustable.
