P2093 code meaning
"A" Camshaft Position Actuator Control Circuit High (Bank 2)
Powertrain system Generic code P20xx codes Check engine light
What P2093 means
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.
P2093 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.4 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2093
- Engine warning lamp on
- Bank 2 intake timing fixed, reduced low-speed torque
Common causes of P2093
- Most likelyBank 2 intake valve wire shorted to an ignition or injector feed
- PossibleFault in a shared engine harness connector
- Less likelyECM output stage defective
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2093 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 0 | Area: fuel and air metering and auxiliary emission controls. |
| 93 | The exact fault in that area. |
What to do next
- Note P2093 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2093
What does P2093 mean?
P2093 means ""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). It is a generic code, so it means the same on every make.
Is it safe to drive with P2093?
Drive gently and only to a workshop. With P2093 the car can go into limp mode (reduced power) to protect itself.
Will P2093 fail an emissions test?
Yes, it can. P2093 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2093 to fix?
Difficulty: medium. A typical repair takes 0.4 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2093 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
