P2093 "A" Camshaft Position Actuator Control Circuit High (Bank 2)
P2093 reports too high a level on the control line of the bank 2 intake phaser valve (actuator A). Table 23OBDG07 shows why High and Low are not tied to one wiring fault: that GM controller switches the valve on the ground side, so it checks for voltage with the driver switched on and calls it a short to power after 1 s, with the lamp after two trips. The 3.6 L LFX (19OBDG03B) uses a high-side driver and looks for the same short with the output off; there P2093 is Type A after 20 of 25 samples. Ford's 2014 code list names P2093 as a lamp code covered only by the continuous monitor. Typical findings are a chafed wire touching an ignition or injector feed. If P2093 and P2089 appear together, suspect a shared supply or connector rather than two valves.
Likely causes
Symptoms
- Engine warning lamp on
- Bank 2 intake timing fixed, reduced low-speed torque
Repair estimate
Typical range across vehicles; the real cost depends on what the testing finds.
