Land Rover Repair: 2002 Freelander SE, electronic control unit, freelander

Question
Hello Nigel

I need the meanings for codes P0606 P1629 & P1628 for my 2002 Freelander SE.

Thanks

Answer
All 3 codes are rationality checks.  P0606 is an ECU (Electronic Control Unit) self check.  The other two codes are checks between the acutal throttle angle to the expected throttle angle.  I would suggest cleaning the sensors and collections, apply di-electric grease, clear codes and see if the codes come back.
