I have code 7717, ereasable.Starts after 5 sec.cranking.Code is coming back.No check engine.Power good.Supply Cam sensor 12V /5V ok.Pattern ok.Problem ?

1.) The CKP sensor is located on the lower right (passenger-side) front of the engine, near the crankshaft pulley. 2.) The ECM is located behind the glove box. It is a rectangular-shape with 5 electrical connectors, each of which has many wires. 3.) Do this instead; unplug CKP sensor, check the yellow/black wire for 12v with ignition on; if not present, repair wire between CKP sensor and PGM-FI relay. Next, measure voltage between CKP yellow wire and ground; there should be about 5v, if not, check for 5v from PCM connector A7; if present, repair wire between ECM and CKP. Next, check voltage between CKP yellow/black wire and brown/yellow wire; if not, repair wire between CKP and ground G101. Next, check for continuity between ECM A7 and ground; if present, repair wire for short-to-ground. If all OK, replace the CKP sensor and with an advanced scan tool, reset the ECM, clear the CKP learned pattern, relearn idle and CKP pattern. If issue not resolved, update ECM software (if not up-to-date) or substitute a known-good ECM.

Sounds like your crank position sensor went out.

Everything sounds ok , May want to check your converter?

FUEL PRESSURE MUST BE 62 LBS. OR GREATER OR IT WILL NOT GROUND INJECTORS, IF ITS OK THEN CHECK YOUR GRAY 12V SUPPLY TO PUMP AT CRANK-UP, YOU MAY HAVE A POOR IGNITION SWITCH.

Yes the car will fail to start due to this error code p1496.Its possible. Description of code P1496 is 5 Volt Supply Output Too Low. But to locate the exact fault you will need to do some troubleshooting. The 5 V ref. can be low for a couple reasons. 5V is supplied to several engine sensors, like the crank, cam, Map, etc. It's not uncommon on chryslers for one of the sensors to short the 5 V. reference voltage and get that code. To check if a sensor is bad and shorting the ref. just check for voltage on the 5V ref as you unplug each sensor. If the 5 V. ref. returns, the last sensor you unplugged is the shorted sensor. It's usually the crankshaft sensor, but not always. If the 5 V. ref. still is shorted after unplugging all sensors that receive 5V. ref, check for 5 V. at the PCM. If it's present at the PCM, there's an open or short after the PCM. If there isn't 5V ref at the PCM, it's probably a bad PCM. That is a 5 volt supply too low. You will want to check the connections at the MAP and TPS sensors. --------

Thanks. keep updated for any more query.you can rate this solution and show your appreciation.

tht is a camshaft sensor code. you probablyhave a sensor just starting to go bad and when it does the truck won't start no more. if you want to look atthe wire haness going to the cam sensor and if it looks good thaan swap the cam sensor.

also if you give the size engine you have i can give you a test to do with a meter to check it. but most of the time if thevehicle is running you can't tell. it has to be broke to tet it. but to re assure you i istall alot of cam sensor nd also crank sensor. so it is a very common problem...goodluckand ask any more question you have.

fuel rail preasure rgulator valve may be faulty

"No Bus" means the data cable going to the (PCM) computer is unplugged, or the PCM has failed and not able to read the information it is being given.
Sometimes just jiggling the PCM causes the ODO "NO BUS" to come on.
Sometimes a bad crank or cam sensor can cause this as well.

Here is the OFFICIAL checklist for the "NO BUS" condition....

Vehicle: 1998 - 1999 Dodge Durango 3.9L
2000 - 2001 Dodge Durango 4.7L
1998 - 2000 Dodge Durango 5.2L
1998 - 2001 Dodge Durango 5.9L



Symptom: Engine will not start. Gauges are inoperative. No BUS message displayed on odometer.



System: Body/Chassis Electrical, Emissions/PCM/Fuel, Engine Electrical



Codes: N/A



Problem 1 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Crankshaft Position (CKP) Sensor.



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) sensor. If 5v is not present, unplug the Crankshaft Position (CKP) Sensor. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit. If the voltage is now 5v, replace the CKP sensor.



Problem 2 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Camshaft Position (CMP) Sensor.



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) Sensor. If 5v is not present, unplug the Camshaft Position (CMP) Sensor. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit. If the voltage is now 5v, replace the CMP sensor.



Problem 3 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Manifold Absolute Pressure (MAP) Sensor.



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire (5v power supply) at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) Sensor. If 5v is not present, unplug the MAP sensor. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit. If the voltage is now 5v, replace the MAP sensor.



Problem 4 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Throttle Position Sensor (TPS).



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire (5 volt power supply) at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) Sensor. If 5v is not present, unplug the TPS. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit. If the voltage is now 5v, replace the TPS.



Problem 5 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted wire.



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire at the throttle position sensor (TPS) or manifold absolute pressure (MAP) sensor. If 5v is not present, unplug all sensors that are connected to the 5v power supply and disconnect the PCM. Check if either 5v power supply circuit is shorted to ground using a DVOM. If the circuit is found to be shorted to ground, repair the wire and the cause of the short.



Problem 6 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Governor Pressure Sensor.



Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) Sensor. If 5v is not present, unplug the large round connector on the driver's side of the transmission. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit. If the voltage is now 5v, remove the transmission pan and check for shorted wiring inside the transmission. If the wiring is OK, replace the Governor Pressure Sensor.


Many times the PCM simply overheats - and changing it will stop the problem.


Thanks for using FixYa - a FixYa rating is appreciated for answering your FREE question.

try checking all the ground circuits comming out of the PCM. and its also not common for a ground driver in the PCM to fail on dodges. also i have seen crankshaft sensors short out and take out pcm communication. so i would start by unplugging any sensor that runs off the 5v supply until the pcm wil talk to the scanner. if you unplug a sensor and communication returns to scanner then replace the sensor. and dont forget to check for good power and ground at the data link conector and PCM
