[[I have the following in my basket:
P0110 - Intake Air Temperature voltage too hi or lo - MAP sensor
P0235 - Boost sensor voltage too hi or lo - MAP sensor
P0514 - Batt Temp rationality - output does not change as expected, can cause other errors
P0579 - Cruise multifunction switch circuit A
P1130 - Unspecified in CRD system - could be anything for those OTHER engines with O2 sensors
P1685 - Unspecified in CRD system
I tested the Check Engine Light by unplugging the MAP, so P0235 and maybe P0110 is related to that test. P0514 may go hand in hand with my occasional battery fault light coming on (suspect the battery has almost exceeded it lifespan).
P1130 - Heated Oxygen Sensor Circuit Low (is that on the exhaust)?
P0579 - Never knew of any issue on cruise control
P1685 - Skim key invalid (equally never tried an invalid key) ]]
Other than the disconnected MAP sensor DTC's, errors from various unrelated points could be corrosion\oxidation in the connectors, frayed wiring, etc - disconnect each connector, scrutinize the pins and wiring - if ok, reconnect and go to the next one - also the battery temp fault can cause several other codes, such as the O2 sensor code, of which sensor the CRD has none of, being a Diesel
