I am learning to address issues with my recently acquired 4.0 l Ranger a somewhat sooner than I had planned. The CEL light came on, pulled the code(s) 116, replaced the engine temperature sensor and thought all was well.

CEL light came back on a few days later - KOEO 111, continuous memory code is 214 - cylinder identification circuit failure, and KOER codes are 536 and 538 which are brake on/off circuit not activated and invalid cylinder balance test due to throttle movement during test.

Has anyone had experience with these particular error codes that will share their experience solving the puzzle? Thanks in advance.

Wouldn't worry about the 536 and 538 codes, probably are a result of the KOER portion of the testing process not being carried out properly.

The 214 means your Camshaft Position Sensor (a/k/a CID Sensor) or it's circuit is malfunctioning. The CID Sensor, and it's related synchronizer assembly, is located behind the upper intake manifold (back toward the firewall), top center of the block.

 

Is there a test procedure for the Camshaft Position Sensor? I fell off the stool at NAPA when he told me that a new one is $258. From reading I understand that this could be that the Camshaft Sensor and Crankshaft Sensor could be out of sync? How would one check this?
This is beyond what I normally get into but am willing to try and solve it. I like a challenge.

Any input is greatfully appreciated.

Continuous Memory DTC 214 indicates an error has been detected in the Cylinder Identification (CID) input signal. The error could be due to a hard fault or an intermittent condition.

Possible causes:

-- Open or shorted harness.

-- Damaged Camshaft Position (CMP);

-- Damaged Ignition Control Module (ICM) (if equipped).

-- Damaged Powertrain Control Module (PCM).

Since your 4.0L has EDIS ignition, you can rule out a damaged ICM as a cause, since the CMP sensor’s signal is not used for ignition timing on EDIS, only for fuel injection timing, which means that the CMP signal does not run through the ICM. So that leaves you with either a bad CMP sensor, a bad PCM, or an open or short in the harness connector somewhere.

Try clearing the code (take negative battery cable off for 20 minutes) and see if the 214 comes back.

 

Thanks for the advice Rockledge. I shall indeed do so. In your opinion, would cleaning all of the connections with contact cleaner be a good preventive measure? e.g. unplug them, spray with contact cleaner and reconnect.

Thanks again for the insight. I shall keep you posted.

Yes. Cleaning the pins and harness connector to the CMP would be a good idea.

Hopefully it's one of those things where cleaning and wiggling the wires around will clear things up. Let us know how it goes.
