2001 Mazda Protege 2.0 ES, recently got a P0421 code and Pending P0660 code.
I replaced a new Pre-CAT and P0421 code is gone. Both code gone after a test drive cycle. no more CEL, but car still stuck in Limp Mode.
I scan the car and showing the following readings under Live Data:
DTC_CNT = 0
Fuel Sys 1 = CL
Fuel Sys 2 = - - -
Load Value % = 15.3%
Engine coolant Temp = 95C
Short Term Fuel Trim = -1.6% to 0.8%
Long Term Fuel Trim = -7.8% to -8.6%
Engine RPM = 706
Ignition Timing Advance 1 = 8 degree to 10.5 degree
Intake Air Temp = 38C
Air Flow Rate = 2.07 g/s
Absolute Throttle rate = 0%
02 sensor B1S1 = 0.075 to 0.83v
Short Term Fuel Trim B1S1 = -1.6% to 3.1%
02 sensor B1S2 = 0.815v
Short Term Fuel Trim B1S2 = 99.2%
Would someone please help to look at the above Live Data and see what next should I do?
Any pointer will be appreciated & Thank you!
