Question about 1998 Dodge Durango

1 Answer

Have code P1682 on 98 dodge durango. I know it's low voltage detected. I pulled the alternator off and had it tested three times and it shows to be good. Have looked at the wireing and everythi

I also pulled the cable off the battery when it was running and it died instanty. The main cable that runs from the alternator to the battery, runs to a fuse box and I havn't checked the fuses yet.

Ck the fuse but this vehicle has a built in voltage regulator in the pcm and you have to either install a different pcm and then have it reflashed for your vehicle or install and external regulator i believe napa sells these as i have replaced quite a few of these in our shop.

What is code 201?


P0201 -PCM detected a fault in the injector or the wiring to the injector. PCM monitors the injector and when the injector is activated. PCM expects to see the voltage pulled "low" or close to zero.
When the injector is switched off, the PCM expects to see a voltage that is close to battery voltage or "high". If it doesn't see the expected voltage the PCM will set this code. PCM also monitors resitance in the circuit. If the resistance is excessively low or high it will set this code.

The causes could be a bad injector. This is usually the cause but doesn't rule out the possibility of one of the other electrical causes

I got two trouble codes on my '02 DODGE Durango SXT. My trouble codes are 1) P0036 2) H025 Can anyone give me advice?


Code 25 is a problem with cam timing, and code 36 is for a problem with the heater circuit for the O2 sensor - bank one sensor two.
The testing procedure for each code would need to be followed to find the problem. You would need a shop manual to get the testing procedure. The codes are not related and the problems may not be constant.

Check gauge/low voltage


May or may not throw a code, have you had the alternator checked, this sounds like a bad alternator and also you charged the batteries but have them tested also, this sounds like an alternator problem.

Dodge durango stalls after starting


There may be a fault code or codes stored, though. Have an engine scan done for trouble codes as a first step in diagnosis. If no codes are present, I would start by investigating the idle circuit-clean the throttle body and have the IAC (idle air control) tested for proper operation. Good luck.

I have a 2001 dodge Durango 4.7 v8. The battery died and the alternator tested bad. I replaced both the battery and alternator. The new alternator within a week stopped working and I replaced it. It was...


it is the regulator that is the problem
a battery will need 14.5-14.8 volts dc to charge and a fully charged battery in good condition will read 13.2 on a multimeter
as you say the regulator is in the ecm so get a good replacement from the wreckers or junk yard or get a reconditioned ecm for those shops that can recondition/exchange

LOw voltage after new alternater was installed, battery is good. Voltage shows about 12 volts when running.


That 12v is probably just battery voltage. If you have a test light try sticking the red wire going to the back of the alternator and see if you have power there. If you do, you very likely may have bought a bad alt... It happens here at the shop all of the time. If you dont have power -look for a fuseable link somewhere between the alternator and the battery and check power on both sides of the link. Also see if there is an ALT fuse in the engine compartment fuse box.

Something is draining the battery


You have a draw and a draw pulling more than a couple hundred milliamps.This will drain the battery in an objectionably short amount of time.. All the things you mentioned and more can cause this draw. The best diagnostic step towards isolating your draw is with meter that reads Volts DC or better yet a test light.(I think) ..disconnect B+ positive battery cable. Install meter or lamp in series with disconnected cable and battery post. You do have some smal draws like computer memories,clocks etc which will show a low amount of voltage hence a very dim test light. If you are drawing heavy ,obviously the meter will show a full blown 12 volts and the lamp bulb will be very bright. Remove fuses,unplug relays,dis-connect devices while watching the voltage or lamp.You should begin to isolate offending item once the circuit has been detected, Generally pulling all fuses individually will tell you at least which circuit is pulling the amps.

Dad's Dodge Durango light problems


The proper way to jump start is to start the car that is doing the boosting first then connect the cables, making sure that the polarities are right, negative to negative and vice versa. The reason for this is that while cranking the car doing the boosting, the the car with the low battery suffer a significant voltage spike since the sudden draw of current will pull the voltage down on a weak battery, and when the car do start, the voltage suddenly goes up, adding to that, the alternator bring the voltage even higher. Electronic circuits are sesitive to these voltage spikes. Still I doubt your problem is caused by these unless theses things you are having problems with are controlled electronic,.
