What are the probable causes of DTC P0201?


Code 201 means there is a problem with the circuit for injector one.
It could be the injector or in the wiring back to the computer.

You mean P0202 , an what engine does yours have ? 2.6 L ,3.3 L , 3.6 L or 5.7 L ?
DTC P0201, P0202, P0203, P0204, P0205, or P0206
The engine control module (ECM) enables the appropriate fuel injector on the intake stroke for each cylinder. Ignition voltage is supplied directly to the fuel injectors. The ECM controls each fuel injector by grounding the control circuit via a solid state device called a driver. The ECM monitors the status of each driver. If the ECM detects an incorrect voltage for the commanded state of the driver, a fuel injector control DTC sets.
Test your fuel injector for cylinder #3 ! Do you know how to do that ?
You probably changed computers for nothing ! Check out this video on testing fuel injector circuits an checking computer driver that controls the injectors , Oh , by the way P0300 P0301 an P0302 are misfire codes , P0300 is a random misfire an the other two are for cylinders 1&2
Testing Fuel Injectors Fast PCM Driver Testing II without scan tool Did you just replace the PCM - engine computer ? Didn't test anything !

Trouble codes p0201 p0203 p0300 p0336


Start with the replacement of the Crankshaft position sensor to address the P0336.
The faulty crankshaft position sensor may be causing the P0201 which is a fuel injector failure to injector #1 and the P0203 which is a injector failure to the injector #3. The failure to the injector will cause the P0300 DTC code which is a code for multiple misfire.
The crankshaft sensor sends signals to the ECM which then would command the injector to pules open and close and the duration of time. If the ECM does not get the right readings, then it's not going to know when to command the injectors to activate.
Start with the Crankshaft sensor (CKP)and then check the injector wires and injectors it self after the (CKP) has been replaced if problem still persists. Good luck and keep me posted, be glad to help you get your car running 100% again soon.

Troble code P0170


Trouble Code: P0170 (3.4L V6 VIN V Auto)
Fuel System Too Rich or Too Lean (Bank 1) Print this code dataprint_icon_codes.gif Number of Trips to Set Code: 2
OBD II Monitor Type: CCM Details
Indicators: MIL Details
Trouble Code Conditions:
DTC P0100, P0101, P0110, P0115, P0120, P0121, P0130, P0133, P0136, P0135, P0136, P0141, P0153, P0155, P0201-206, P0300, P0301-P0306, P0401, P0402 and P0441 not set, engine running in closed loop at a stable engine speed, and the PCM detected the lean or rich fuel trim correction value was more than or less than a calibrated limit in memory.

  • Base engine "mechanical" fault affecting one or more cylinders
  • Fuel control sensor is out of calibration (i.e., ECT, IAT or MAF)
