Replace the throttle position sensor when this sensor fails the idle speed fluxuates may cause the trans to shift oddly also

Engine runs rough and stalls sets a p0068 code on a 05 dodge durango


P0068-MAMFQLD PRESSURE/THROTTLE POSITION CORRELATION
' Image
Theory of Operation
This DTC sets when an unexpected high intake manifold air flow condition exists that
can lead to increased engine speed and puts the NGC into a High Air flow Protection
limiting mode. The High Air flow Protection feature includes RPM limits for when a
Throttle and or MAP sensor limp-in fault is present.
When Monitored
During all drive modes.
Set Condition
If vacuum drops below 1.5Hg with engine RPM greater than 2000 RPM and closed
throttle. One Trip Fault. Three good trips to turn off the MIL.
Possible Causes
-VACUUM LEAK
-RESISTANCE IN THE (FS56) 5-VOLT SUPPLY CIRCUIT
-(FS56) 5-VOLT SUPPLY CIRCUIT SHORTED TO GROUND
-RESISTANCE IN THE (Kl) MAP SIGNAL CIRCUIT
-(Kl) MAP SIGNAL CIRCUIT SHORTED TO GROUND
-RESISTANCE IN THE (FS55) 5-VOLT SUPPLY CIRCUIT
-(FS55) 5-VOLT SUPPLY CIRCUIT SHORTED TO GROUND
-RESISTANCE IN THE (K22) TP SENSOR NO. 1 SIGNAL CIRCUIT
-(K22) TP SENSOR NO. 1 SIGNAL CIRCUIT SHORTED TO GROUND
-RESISTANCE IN THE (K900) SENSOR GROUND CIRCUIT
-MAP SENSOR
-THROTTLE POSITION SENSOR
-PCM
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.

Get codes p0068 and p0108


codes p0068 refer to Manifold pressure sensor/mass air flow sensor--throttle position correlation--causes ---wiring---map sensor---maf sensor--mechanical fault.
code p0108 refers to manifold absolute pressure(map) sensor/barometric pressure (BARO) sensor--high input. causes ---wiring short to positive---map sensor---baro sensor---ecm.

2003 neon code p 0068


Hi there:

P0068 - MAF/MAP Sensor throttle correlation



I suggest to check the snorkel going to the MAF (Mass Air Flow) sensor. Check for rips, cracks or if a tube has fallen off.



Hope helps.

P0068 on a 2006 Dodge Ram 1500 SLT. Rough "hunting" for idle. Momentary lag/loss of power from a stop. Random RPM changes while at a constant speed. Sometimes it feels like it drops out of gear...


P0068 Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of power
- Engine rough idle Possible causes - Large vacuum leak
- Leaking air duct system
- Mass Air Flow (MAF) poor electrcial connection
- Manifold Absolute Pressure (MAP) poor electrcial connection
- Faulty Mass Air Flow (MAF) sensor
- Faulty Manifold Absolute Pressure (MAP) sensor
- TP sensor not seated properly.
- Faulty Throttle Position (TP) sensor.
- Dirty throttle body
When is the code detected? The Powertrain Control Module (PCM) monitors operation rationality check by comparing sensed throttle position to mass air flow readings
P0068 DODGE Description The Powertrain Control Module (PCM) monitors a vehicle operation rationality check by comparing Throttle Position (TP) to Mass Air Flow (MAF) readings. If, during a self-test, the comparison of the TP sensor and MAF sensor readings are not consistent with the calibrated load values, the test fails and a diagnostic trouble code is stored in continuous memory.

P0121 and p0068 on a 2003 dodge ram 1500 replace the throttle position sensor and the idle air sensor at the same time then ran for a week with no problems then the truck started idling up at random then...


P0121 The Throttle position sensor is a potentiometer that measures the amount of throttle opening. As the throttle is opened, the reading (measured in volts) goes up. The powertrain control module (PCM) supplies a 5 Volt reference signal to the throttle position sensor (TPS) and usually a ground also. A general measurement is: at idle = .5 Volts; full throttle = 4.5 Volts. If the PCM detects that the throttle angle is greater or less than it should be for a specific RPM, it will set this code.
Potential Symptoms Symptoms of a P0121 trouble code could include:
  • Malfunction Indicator Lamp (MIL) illumination (Check Engine Light or Service Engine Soon light)
  • Intermittent stumble on acceleration or deceleration
  • Blows black smoke on acceleration
  • No start
Causes A code P0121 may mean that one or more of the following has happened:
  • TPS has intermittent open or short internally
  • Harness is rubbing and causing an open or short in the wiring
  • Bad connection at the TPS
  • Bad PCM (less likely)
  • Water or corrosion in connector or sensor
Possible Solutions 1. If you have access to a scan tool, see what the idle and WOT (wide open throttle) readings are for the TPS. Check if they're close to the specifications mentioned above. If not, then replace the TPS and re-check.

2. Check for an intermittent open or short in the TPS signal. To do that, you can't use a scan tool. You'll need an oscilloscope. The reason is because scan tools take samplings of many different readings over just one or two data lines and can miss an intermittent drop out. Hook up your oscilloscope and watch the signal. It should sweep up and down smoothly with no drop outs or spikes.

3. If no problems were noticed, perform a wiggle test. Do this by wiggling the connector and harness while watching the pattern. Does it drop out? If so, replace TPS and re-check.

4. If you have no TPS signal, check for 5 Volt reference at the connector. If it's present, check the ground circuit for open or shorts.

5. Make sure the signal circuit isn't 12V. It should never have battery voltage. If it does, trace circuit for short to voltage and repair.

6. Look for any water in the connector and replace TPS as necessary.

2004 Ram 1500 1/2 ton 2WD. Code P0068 is what is coming up. Truck will idle high/low at times and will die sometimes when I stop. Engine light is on, I have checked for vac leaks and cleaned the sensor...


It's a map/tps sensor correlation code, essentially it means the map sensor reading isn't what's expected with the tps reading and vice versa! It sounds like your tps sensor is probably bad or the circuit to one of those 2 sensors.

Hope helps (remember rated this).

  • P0068 MAP/MAF - Throttle Position Correlation

  • P0108 Manifold Absolute Pressure/Barometric Pressure Circuit High Input
    Have u had any work done on the engine lately or anything done under the hood? looks like something in the area of the MAF sensor is disconnected or the sensor itself is disconnected, all the codes are related.
