We have a 2002 Explorer XLS at work. I plugged in my code reader and got the following codes:
P0125 - Closed Loop Fuel Control Insufficient Coolant Temp
P0136 - O2 Sensor Circuit Malfunction (Bank 1 Sensor 2)
P0138 - O2 Sensor Circuit High Volts (Bank 1 Sensor 2)
P0152 - O2 Sensor Circuit High Volts (Bank 2 Sensor 1)
P0175 - System Too Rich (Bank 2)
P1151 – Manufacturer Controlled Fuel & Air Metering
P1152 – Manufacturer Controlled Fuel & Air Metering
What do I need to do to make these go away? I thought it was the t-stat so I replaced it (needed it anyhow) and the CEL codes are still there. Please help! Thanks in advance.
