CEL Light, Codes, Need Diagnosis
Hey guys! I need someone smart with the CEL codes. It seems bizarre to me that all four O2 sensors would error out at the same time.
This is for my '97. I can duplicate these codes any time at WOT. Surprisingly, almost all last winter, the codes went away. Now that summer has returned, so have the codes. What do you think?
P0131 H C (Heated Oxygen Sensor (HO2S) Circuit Low Voltage Bank 1 Sensor 2)
P0137 C (Heated Oxygen Sensor (HO2S) Circuit Low Voltage Bank 1 Sensor 2)
P0151 H C (Heated Oxygen Sensor (HO2S) Circuit Low Voltage Bank 2 Sensor 1)
P0157 C (Heated Oxygen Sensor (HO2S) Circuit Low Voltage Bank 2 Sensor 2)
P1571 H (ASR Desired Torque)
I don't seem to have any other symptoms, other than during acceleration it might be hesitating a little bit at lower RPM's.
Thanks, I really appreciate your help.
