REMOVAL - 4.7L
The Camshaft Position Sensor (CMP) on the 4.7L V–8 engine is bolted to the front/top of the right cylinder head (CMP Location—4.7L Engine).

It is easier to remove/install sensor from under vehicle.

Raise and support vehicle.
Disconnect electrical connector at CMP sensor (CMP Location—4.7L Engine).
Remove sensor mounting bolt (CMP Location—4.7L Engine).
Carefully twist sensor from cylinder head.
Check condition of sensor o-ring.
See picture for sensor location.

SOURCE: i have code p0137 coming up on my 2003 jeep grand

P0137 - Oxygen O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2)

Essentially the same as P0136, P0137 refers to the second oxygen sensor on Bank 1. P0137 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 2 is located to the rear of the catalytic converter and should produce an output signal relative to oxygen storage capacity of the catalytic converter. This rear (sensor 2) sensor is less active than the signal produced by the front sensor. However, if the ECM senses the sensor is inactive, this code will set.

Symptoms: There may be no visible symptoms to the driver, other than the MIL (Check Engine / Service Engine Soon) illumination.

Causes: A code P0137 may mean that one or more of the following has happened:
* Faulty o2 sensor Exhaust leak near the rear sensor
* Plugged catalyst
* Short to voltage on O2 signal circuit
* High resistance or open on O2 signal circuit

Possible Solutions:
* Replace faulty sensor
* Repair exhaust leak near the rear sensor
* Check for restriction in catalyst and replace as necessary
* Repair short, open, or high resistance on o2 signal circuit

1686, rigth out of fsm

Trouble Code: P1686 4.7L
No SKIM Bus Messages Received
Number of Trips to Set Code: 1
PCM details.
Trouble Code Conditions:
Engine started; and the PCM did not detect any MIC (I/P Cluster) messages over the Data Bus circuit for 20 seconds.
Possible Causes:
  • Data Bus circuit from MIC to the PCM is damaged or it is open
  • Instrument Cluster is damaged or has failed
  • PCM unable to communicate with the Instrument Cluster
  • PCM has failed
this means, the PCM can not talk to the I/P cluster puter.
comm fail.
even wilder guess is PCM talks to KEY via cluster so if cluster dead
so be key.

What is error code p1686 on jeep Cherokee 2001


Hello lhernandez79,

The P-1686 is NO SKIM BUS MESSAGE RECEIVED.

SKIM stands for Smart Key Immobilizer Module.

One way I have solved this code is to disconnect the battery for about five minutes this resets the module.

I hope this helps.
