Question about Chevrolet Metro
There is a diagnostic route on the PO705 code,which involves hooking up a scan tool,and verifying sensor functions.It can also involve checking continuity of the circuit,and PCM commands.The majority of the time,replacing the sensor in question resolves the problem,but after replacement,the sensor needs adjusting to be correctly aligned,to give the correct reading in each gear range.If replacing the sensor does not repair the problem,then it's down to checking the wires involved in the circuit for continuity.If the wires check out OK,then it's going to be checking the PCM (computer) for proper commands and outputs.Resolving the code will likely repair the problem you are having getting the vehicle out of Park.The "stuck in Park" problem has to do with the shift interlock,where you have to press the brake pedal down to disengage the shifter.It is possible you have two separate problems,but repair the PO705 code first,and see what happens with the interlock problem.The PO705 HAS to be repaired to pass inspection anyways.I guess i didnt explain,but the PRNDL switch is the sensor that tells the vehicle computer (PCM) which gear the trans is in..Park,Reverse,Neutral,Drive,Low (PRNDL).Good luck.
