P 1294 registers and causes the MIL or check engine light to illuminate if the PCM (power control module) can not properly maintain a preset idle point withing 200 RPM(revolutions per minute). This can be caused by a faulty or sticky IAC solenoid (idle air control), or a vacuum leak and possibly various other factors.

In particular on a Dodge 3.3L there is a small 5/16 inch rubber hose about 5 inches long just below the throttle body. This connects to the throttle body directly. Due to heat and deterioration from age it can actually split on both ends allowing unwanted, and unfiltered air to enter the intake manifold, through the throttle body. Replacing this hose could eliminate the P 1294. I had this problem on a 2003 Grand Caravan with 120,000 km.

Q.1 How can you determine the no. of redundant bits in Hamming Code error correction technique? Q.2 Compare line discipline methods ENQ/ACK and Poll/Select? Q.3 What the receiver wil receive if the check sum method is applied to the following bit? 10101001 00111001

Codes are cleared and computers are reset with a scan tool.

The internal test for the code has to run and pass three times in a row for the light to shut off. Most only run once a start, and not all will run every time. It could take a while.

Trouble code P1739 means: TCM A/T controller circuit

Trouble code P0122 means:Throttle/pedal position sensor/switch A circuit low input

Trouble code P0733 means:Gear 3 incorrect ratio

Trouble code P0506 means: Idle control system, rpm lower then expected

take the sensor off and soak it in gasoline for about 20mins and reinstall it....
