Camshaft Position Sensor Circuit Intermittent
O2 sensor circuit malfunction, Bank 1 sensor 2. Check the O2 sensor after the catalytic converter.
O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)
Code 41 is an "air temperature sensor" fault. (KA24E Engines only). Check the circuit for "open circuit" or "shorted circuit" first. Change sensor.
PO137 (Sensor Circuit low voltage Bank 1 Sensor 2) This is the O2 sensor behind the Catalytic Converter on the driver's side. Check the wiring on that sensor before proceeding. More than likely replacing that sensor will solve the problem especially if you have over 75,000 miles on the vehicle. But there is no guarantee that will fix it.

P1401 is DPFE sensor circuit high, check out this tutorial to replace the sensor on your Ford
Oxygen sensor circuit open. Check if the wire is plugged in or broken. If it is then replace the O2 sensor.
There are several ways to check your mass airflow sensor. You can measure the output voltage of the sensor, measure the hot film frequency of the sensor, or check the self-cleaning circuit. eHow has a great article that elaborates on these steps.
Trouble code P0150 means:O2 sensor circuit malfunction (bank 2,sensor 1)
Trouble code P0130 means:O2 sensor circuit malfunction (Bank 1 Sensor 1)
Trouble code P0131 means:O2 sensor circuit low voltage (Bank 1 Sensor 1)
P0042 HO2S Heater Control Circuit (Bank 1 Sensor 3)
P0520 Code Engine Oil Pressure Sensor/Switch Circuit Malfunction
O2 sensor circuit bank 1 sensor 2 no activity. Check the wiring and connections to bank 1 sensor 2 O2 sensor, if all looks good replace the sensor.
The check engine code PO136 means the O2 sensor circuit malfunction
P0141 is heated oxygen sensor circuit malfunction you need to check the supply voltages to the sensor.
Coolant temperature sensor circuit high. Check the sensor near where the upper hose attaches to the engine to see if plugged in.
O2 sensor circuit slow response. Bank 1 sensor . Suggest you check this out with a OBDII. can be done at Pep Boys.......
Trouble code P0156 means:O2 sensor circuit malfunction (Bank 2 Sensor 2)
IAT sensor 1 circuit high input. Check to see if the Intake Air Temperature Sensor is unplugged.
O2 sensor heater circuit malfunction (bank 1 sensor 1). You probably have a burned out Bank 1 Sensor 1 O2 sensor. Also check the wiring at the sensor for damage.
Trouble code P0387 means:Crankshaft position sensor B circuit low input
