Dodge Dakota Warning Lights and Trouble Codes
My engine light came on and the code is P0161 and it went off within a week and came back on and remains on, a month later. Any ideas on where to find the malfunction and correct the problem?

O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 2).
Sensor 2 I think is the rear O2 sensor. I don't remember if Bank 2 is the right or left. Check to make sure that the connections are good and clean. If it persists, then the O2 sensor will probably have to be replaced.
When it does this how does the engine idle?
Have you tried stopping the vehicle, shutting the engine off, then restarting? What happens then?

btw you can read your trouble code by turning your ignition key 3x off on (donot start) and the trouble codes will appear in the odo....
Something else might be going on with your Dakota. You are only the second one I know of that's had an O2 sensor failure on a 4.7, and the only one that's replaced all four!
By any chance have you had any over charging problems with your truck?

If you ever get a chance, measure the terminal voltage after the vehicle has been driven for some time with minimal use of the accessories (lights, fan, etc.) and the engine running. Take note of the air temperature.

I will ck the voltage though what should it read? wouldn't the volt gauge in the truck tell if I was overcharging though?
When I stated "over charging," I meant that the charge rate was more than required to keep the battery at specific gravity. The voltage regulator could be causing an incremental increase in the charge rate, not enough to boil over a battery in a short time, but enough to overheat the plates and cause eventual warping as well as aggresive electrolyte evaporation.
Unfortunately, the voltage gauge on the instrument panel is probably not accurate enough to be a reliable indicator to make a judgement on charge rate. However, the the Powertrain Control Module gets a signal from the battery temperature sensor mounted in the bottom of the battery tray. If that sensor's bad it may be falsely triggering a slight overcharge rate. This would be an item to check, for sure.
The charge rate specifications are as follows:
-20 F = 14.9 to 15.9 volts
+80 F = 13.9 to 14.6 volts
140 F = 13.3 to 13.9 volts
above 140 F = less than 13.9 volts
NOTE: Temperature is ambient at the battery.
NOTE: Voltage is measure at the battery terminals.

the check engine light came on.
i have no problems with the truck at all.
how do i reset the light myself?
If it was something like a loose fuel cap, the light will reset itself after a few days.

The "PRM doesn't reach target" might be caused by a bad throttle position sensor, also a common problem. Or, you have a binding Idle Speed Solenoid (or Motor, depending on the year).

P0340 - (M) No CAM signal At PCM No fuel sync.
I am assuming that this is a faulty or shorted Crankshaft sensor but I am not sure. Looking for a little advice on possible solutions and or the location of this sensor and any tips on changing it.
P1494 - (M) Leak Detection Pump Sw or Mechanical Fault Incorrect input state.
This code did not show up until just after taking the vehicle to the dealer for an oil change. I strongly suspect intentional damage at the dealership, but I am powerless to do anything about it.
Anyhow any additional info on the two engine codes above will be appreciated.

Dusty

I have a 2001 dak quad cab 4x4, auto, 4.7 V8, I love this truck, if I do not change the sensor what will adverse affects be on my Dak?

Self erasure feature is rather complicated, but in the case of emissions related DTCs they should erase with three "Good Trips" if the fault has been repaired.
The definition of a Good Trip has different definitions depending on type of fault, but basically once the vehicle completes three cold start to full warm up and drive cycles, the fault will clear on its own. Some faults only clear after 40 restarts.

Would appreciate any help. Thanks in advance.

now the brake light stay on and when I put it in drive it blinks. How do I
reset the light.
Today I started my truck and had brake light and ABS light come on. Speedometer did not register speed at first. Later at 60 MPH, the speedo would flop about anywhere from 5 to 10 MPH to 70 MPH. Gas consumption on the computer would register anywhere from 0 mpg to 40 mpg. Finally the check wallet light came on (CEL).
When I got home, I checked obd codes by switching off and on three times and got a P0500. Search here did not get a hit. I checked Yahoo and found speed sensor bad is what 500 means.
Is this a DIY replacement for an old fart? Cost?
