Error Codes P0113, P0118, P0122, P0197, P0500

Dear All,



I have a Rover 25, 2002, 1.4L, petrol.



It just about goes but runs rough, especially at low revs/idling.



On idle the revs sometimes to start to fluctuate increasingly until it stalls



I have changed the:



Spark plugs

HT leads

Coil packs

TPS sensor

IAC sensor

Lamba sensor



I have reset the TPS using the `pump the throttle' trick.



But all to no avail.



I am receiving the following diagnostic codes:



P0113 Intake air temperature circuit high input Inlet air temperature short to battery P0118 Engine coolant temperature circuit high input Coolant temperature input – short to battery P0122 Throttle/Pedal position sensor/switch A circuit low input Throttle potentiometer volts input short to ground P0197 Engine oil temperature sensor low Oil temperature reading – short to battery P0500 Vehicle speed sensor malfunction Vehicle speed sensor – implausible signal







Any suggestions?



Thanks in advance for any pointers or assistance.



Gavin.
