on the throttle body
It's located in the engine compartment. Undernead the air filter. You can look under Throttle position sensor to view pictures of it.
Have some one professional adjust your TPS (throttle position sensor)
throttle postioning sensor is bad
Throttle position sensor. With the AC turned on, it causes a greater load on the engine, and a slightly decreased idle speed. The throttle position sensor would detect this immediately and raise your idle to where it would normally be if the AC wasn't running.
On the 2000 626 it is directly under the air filter box.
I had the same problem on my 98 Mazda 626 and the O2 sensor was faulty.....
where is the location of all o2 sensars in 99 Mazda 626
On a typical 4-cylinder 626, the starter motor is located on the lower end of the engine, to the right of the transaxle (removal would require raising the vehicle and properly securing it with appropriate jack stands). On a typical v6 626, the starter motor is located beneath the throttle position sensor, knock sensor, distributor, and other electrical connectors that interfere with the proper removal. acc083
Trouble code P0340 means:Camshaft position sensor circuit malfunction
Yes, it has a speed sensor, about $125 online.
Mazda 626 frm 1996 doesn't have O2 sensors, have you ECU/PCM inspected, it might have a minor damage.
the ABS sensor is bad.
