I have an 05 Dodge truck with the 5.7 hemi and it's reading a p2302 and a p0137 code. Where should I look to rectify the problem and clear the codes?
The P0137 is indicating that an oxygen sensor is shorting to earth. Simply check the connections and wiring for all oxygen sensors for integrity, the oxygen sensors are located on both the exhaust manifolds (one before the catalyst and one after making a total of 4) Note that each oxygen has four wires to it, two are for the integral heater element within each sensor and the other two wires are the signal wires.
The P2302 indicates a problem with the low tension supply to the ignition coil. I suspect that the error might actually have its root cause in the short to the oxygen sensor; parasitic power loss through the short to the oxygen sensor from the coil. Solve the oxygen sensor and the other problem may just be solved at the same time.
