1999 Mazda 626

Hello Friend(s),

My M.626 does not pick-up speed until after a 5Km drive and when ascending a slope, it almost trotts.

I got the following codes after running a scan:

P1101 - Mass Airflow Sensor Circuit out of self test range

P1116 - ECT Sensor Circuit out of self test range (what is ECT?)

P1127 - HO2S Bank 1 Sensor 2 Heater Not on during key on engine running self test - (whats the HO2S Bank 1 Sensor?)

P1474 - Fan control (Primary winding) circuit (What is the primary winding circuit)

P1479 - Fan control (Condenser Primary) circuit

P1650 - Power steering Pressure Switch out of range fault.

Please I need some knowledgable member to kindly explain to me what these codes and descriptions require me to do in order to fix this machine back to its top performance.

I will greatly appreciate your replies.

That's a lot of codes...did they all come at once or over time?

How old is your battery and what's its condition as well as all connections/cables?

A dying battery can cause all kinds of weird codes to pop up.

alot of the codes are for the conditions not being met when the self test was done. you need to clear them and them and do the self test correctly and see what comes back.

THanks guys.... I 'll erase the codes and see what happens next.

But what about the slow pick-up speed?

Is there some advice I could use?

you could have a bad mass air flow, they do go bad, but first look at the air duct from the mass air flow to the throttle body and make 100% sure it is not split or cracked.
