Has code p0620

The code belongs to generator function. Check the easy stuff first. Check grounds around the generator and tighten them. maybe even spray WD40 for good measure. Check the plug-in and wiggle it at the rear. Is it tight? Is the charging system generally working correctly? Finally, there could be a bad PCM - power control module.

First check voltage on your battery with a multimeter a fully charged batt should be 12.6 bolts . Disconnect the battery from the car check voltage, second tyical voltage regulator maintain voltage between 13.5 and 15.5 . 15 when cold and 13 when hot. The regulator allows higher voltage to force electrons into you batt. If batt voltage is under12volts change batt. Is your regulator does not maintain 13 or above change alternator or alt regulator. Good luck

Follow the link for tips on this fault code, bye the way it is P and the number zero not P and the letter "O" P0620 Generator Control Circuit Malfunction

code po620 refers to alternator control--circuit malfunction===causes--wiring---alternator --- battery---ECM
Check that the wiring is good and terminals are tight. Have a load test done on the battery to check for failing cell that will not take a charge. Ensure that the battery posts and terminals are shiny clean. Have the alternator bench tested for out put.

P0620 - Generator Control Circuit Malfunctionhttp://engine-codes.com/p0620.htmlForum CodePossible causes- Failed Generator/Belt
- Battery charge
- PCM controlled generator
- PCM failure
- Open or short generator circuit When is the code detected?The PCM has fault detection circuitry which monitors the state of the generator turn on signal circuit. If the fault detection circuit senses a voltage other than what is expected, this DTC will set. The voltage regulator also contains fault detection circuitry. If the regulator detects a problem, the regulator will ground the generator turn on signal circuit, pulling the voltage low. This also causes the PCM to set the DTC.

Trouble Code: P0340

No Camshaft Position Sensor Circuit Failure

Possible Causes:


CMP Sensor connector is damaged, open or it is shorted.CMP Sensor signal circuit is open or shorted to ground or to battery voltage or 5v supply circuit.CMP Sensor 5v supply circuit is open or shorted to ground or to battery voltage.CMP Sensor ground circuit is open.CMP Sensor is damaged or has failed.CKP Sensor is damaged or has failed.PCM has failed.Trouble Code: P0700

Automatic Transmission Control System Malfunction

Possible Causes:


.The presence of this code means the TCM detected a problem.TCM related Sensor has solenoid is damaged or has failed.This code is for information only - check for other TCM codes.TCM or PCM has failed.Sorry but the PO620 is not listed.

hi, this is an article that will tell you the meaning of code. and I think this tool can clear the code out. hope help.

P1130: Most likely you have a bad oxygen sensor. This would be the first oxygen sensor if you have more than one meaning the one closest to the engine and BEFORE the catalytic converter. They're pretty common and inexpensive enough where I'd recommend changing that first and see if the light goes out on it's own.Hope this helps Tim

i am receiving a code u0101 on my 2005 dodge durango. can you help me. i think it has something to do with the tcm but i am not sure. "LEN"
