Question about Dodge Ram 1500

1 Answer

I have a 2003 Dodge Ram 1500 with a 5.9. It has been occasionally getting Error Code #P0103. I have replaced all spark plugs, wires and distributor cap & rotor. I just got the same error code the other day. Also, it seems to only throw the code when I start the engine. What else can I check?

Hi,

This code refers to :-

P0103 Mass Air Flow (MAF) Sensor Circuit High Frequency

A code P0103 may mean that one or more of the following has happened:

* The MAF may be disconnected, or a wiring connection may be bad
* The MAF sensor may be damaged
* The vehicle computer may be faulty (very rare)

Possible Solutions
The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:

* Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
* Inspect for any air leaks near the MAF sensor.
* Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
* Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
* Replace the MAF sensor.

Good Luck!!

Thanks!!

While driving truck there was a popping noise, motor turned off . Distributor cap and rotor along with spark plugs and wires changed. Truck still won't start. 2003 dodge ram 1500 5.9 litre


5.9 aren't prone to this, But pull the distributor cap. Have someone crank the engine and watch to see if the rotor moves. Also put the number one piston on top dead center on the compression stroke (remove the spark plug to check compression side). See where the rotor sets compared to a diagram At top dead center.. Sounds like the chain broke (unlikely) or jumped.

My 2003 RAM doesn't always wanna start but all the electrical stuff always works. I tested my battery and starter there both fine. I'm at a loss for what else it could be


You may have a cracked distributor cap. But first, disconnect one of the spark plug wires and insert a spark plug into it. Touch the plug to a good ground, such as the engine block. Have a friend try to start it. Use insulated pliers to hold it, or you could get a good jolt. If you see the plug firing, then its not an electrical issue, Probably a fuel problem.

I have a 2002 dodge ram 1500 and need to replace distributor cap. and roter Can anyone tell me where it is .


What size of engine do you have? OR you can follow the spark plug wires. Start at the engine, put one in your hand and follow it to the other end. Where it stops is the top of your distributor cap. If you have a 5.2L engine it will be on the top at the back of the engine, you will have to remove the air filter to get at it.
