I have a 05 Dodge ram 1500 90,000mi. and it start to bog and eng.light came on my codes were p0129-p0405-p0340-p0868 and pending codes were p0129-p0325-p0330-p0405-p0340. I had put a new map sensor in cleared codes and then I had a hard start truck hade high idle but throttle bog at 3000 rpms my new code is p0340 and I changed the cam position sensor. code stays the cam tone ring is in good shape. I don't know where to go next.

Question edited for clarity. Please always quote DTC Codes in full. '129' is not the same as 'P0129'. Single numerical codes are usually computer communication codes.
Question moved to model category.

When you did all this work, did you disconnect the battery?
Did you reset the security system and engine immobilizer?
Is the anti-theft light flashing, flashing fast or on steady?

Trying to figure out how to reset the check engine light on your RAM 1500? You can use the following three-step process to get the job done in no time:

• Find your battery under the hood and disconnect the black/negative cable.
• Wait 20 minutes for the power reserve to expire. The RAM 1500 check engine light should reset automatically during this time.
• Now, just reconnect the black/negative cable. You're ready to get back to work.

If your check engine light is still on after you've gone through these steps, you may need to drive for 50 miles or so in order to reset the computer. If this short driv

Exhaust gas recirculation sensor is what that code comes up to be

• egr valve
• egr sensor
• cam shaft sensor
• barometric pressure sensor (map sensor)

vacuum leak somewhere, out of time, broken timing belt or missing teeth.

Let's start with the codes.

Po129 refers to barosensor

Po344 is a code for the camshaft position sensor

Po339 crankshaft position sensor

Po340 camshaft position circuit malfunction

Po335 crankshaft POS sensor malfunction

Po122 throttle pedal position

Item 2,3,4,5 relate to each other that s camshaft and crankshaft position sensors. Since both already show a malfunction code, it would be advisable to change.

Sometimes other codes show up because there is a relation but not that the item is bad.

P0868....Transmission Fluid Pressure Low

The DTC P0405 is for (Exhaust Gas Recirculation Sensor Circuit "A" Low)

DTC P0406 is for (Exhaust Gas Recirculation Sensor Circuit "A" High)

This would indicate a problem with the EGR valve sensor, or the EGR valve itself is malfunctioning.

Dodge/Chrysler EGR valves are known to be unreliable. The one on my wife's 05 Grand Caravan died in the 40k miles range.

They are not really serviceable. The usual fix is replacement. Part will be between $50 and $150 depending on where you get it. Installation most of the time is 2-4 bolts and the harness.
