2004 Explorer XLT 4.0 V6 4x4
Approx 136.5K
Truck starts fine, idles fine, shifts fine in all gears, and drives just fine. Problem is randomly (and sometimes I can force it to happen) I get a wrench light sometimes with a Service Engine Soon light and sometimes without. 4x4 seems to work fine, I can put it in 4 high and 4 low. I never use 4 low and leave it in Auto 99.9% of the time.
Has happened during idle, cruise, light acceleration as well as heavy acceleration. Can happen cold or warm. Goes into Forced limited mode which cuts power but otherwise drives fine.
If it's just the wrench it goes away if I cycle the truck on and off, but comes back anywhere from 50ft to 50 miles later. Lately I seem to get it once or twice a day.
Generic reader shows P2106 and P0606 only.
Bought a USB reader and used FORscan to get the messages below. The same codes with the exception of the P1812 show up with no wrench or SES light.
I've only owned it for a few thousand miles. The previous owner did take good care of it and replaced a lot of stuff over the years.
Since I've bought it I've done the following:
Deleted balance shaft chain (BS tensioner had failed) and recovered broken plastic and metal leaf from girdle.
Replaced primary crank to jackshaft tensioner (didn't fail but since I was in there...)
Replaced both hydraulic tensioners
Replaced the Crank Position Sensor and the Harmonic Balancer.
Replaced the Throttle position sensor on the TB and cleaned the TB.
Changed all fluids (F&R diffs including friction modifier in rear, coolant, transfer case, trans fluid, oil)
Serp belt + idler + tensioner
UCA's which I disconnected the ABS wires and forgot to plug them back in.
I've also checked all fuses, and checked for bad grounds and frayed wires.
At this point I'm out of ideas. Was hoping to get a year or two out of this and pass it along to my brother, but I'm really starting to not trust it. It's never left me stranded but this wrench/SES stuff is really annoying me.
Here's versioning and modules from FORscan:

Code:
===PCM DTC P0606-FF===
Code: P0606 - ECM/PCM Processor
Module: Powertrain Control Module
Diagnostic Trouble Code details
ECM/PCM Processor
Faulty or damaged PCM.
RAM / ROM circuit failure.
===END PCM DTC P0606-FF===
===PCM DTC P1000-FF===
Code: P1000 - On-Board Diagnostic (OBD) Systems Readiness Test Not Complete
Module: Powertrain Control Module
Diagnostic Trouble Code details
Check of all systems is not complete since last memory clear.
--Possible Causes--
- The vehicle is new from the factory and has not yet been through a complete OBD Drive Cycle.
- The battery or PCM has been disconnected.
- An OBD monitor failure had occurred prior to completion of an OBD Drive Cycle.
- The PCM DTCs have been cleared as part of a service process.
Note: The only way P1000 can be cleared (removed) from memory is when all of the OBD monitors have been successfully completed during normal vehicle operation.
P1000 cannot be cleared from the PCM when: 1. The thermostat is stuck open and a DTC is not generated. 2. There is an open VSS circuit and a DTC is not generated. 3. If the vehicle has a Power Take Off (PTO), the circuit is shorted to VPWR or B+, or the PTO is ON during Self-test.
The purpose of the Diagnostic Trouble Code DTC P1000 is to indicate that not all of the On Board Diagnostics OBD monitors have yet been successfully completed. You may also refer to the OBD Drive Cycle defined under the Powertrain Control/Emission Diagnosis Manual-Diagnostic Methods or the Owner's Manual.
Remember: It is not necessary to remove P1000 from the Powertrain Control Module PCM by driving the vehicle.

===PCM DTC P2106-FF===
Code: P2106 - Throttle Actuator Control System - Forced Limited Power
Module: Powertrain Control Module
Diagnostic Trouble Code details
Throttle Actuator Control System - Forced Limited Power
Possible causes are:
Harness wiring
Accelerator Pedal Position Sensor
Throttle Body Assembly
Throttle Position Sensor
PCM

===OBDII DTC P0606-C===
Code: P0606 - ECM/PCM Processor
Status:

===4X4M DTC P1812-2F===
Code: P1812 - Four wheel drive mode select circuit failure
Status:
- Previously Set DTC - Not Present at Time of Request
- Malfunction Indicator Lamp is Off for this DTC
Module: 4X4 Control Module
Diagnostic Trouble Code details
Four wheel drive mode select circuit failure
--- Possible Causes --------
P1812 can be generated by:
-Open 4-Wheel Drive Mode Switch
-Suspect 4-Wheel Drive Mode Switch
-Suspect Generic Electronic Module
NOTE: For Vehicles with 4x4 Option
If you encounter this code when you are in 4x4 Low mode, rerun the Self-Test in the 4x2 High mode. If you still generate code P1812, there is a 4-Wheel Drive Switch/Circuit problem.

===4X4M DTC U2023-2F===
Code: U2023 - Fault Received from External Node
Status:
- Previously Set DTC - Not Present at Time of Request
- Malfunction Indicator Lamp is Off for this DTC

Diagnostic Trouble Code details
Fault Received from External Node
This DTC may be caused by :
Short circuit on the CAN line.
Open circuit on the CAN line.
There is a time out between two modules on the CAN bus
There is Interference on the CAN bus
There may be other modules on the CAN communication data line that are not communicating and are timing out.
Note:
DTCs that start with 'U' are faults which occur during module-to-module communication.
Modules should never be replaced based only on a 'U' code. These codes do not always indicate a problem, and can be caused by normal diagnostic functions, carried out on the vehicle.
