These are taken from the D2BC.co.uk site, they're for a Disco2 but as the Td5 is essentially the same they should be a good guide:
"MAF(air flow) = 55-60 at idle growing with revs up to 600 or above at 3000+rpm AAP(ambient pressure) = real ambient pressure on barometer in kPa, around 100 must drop up to 2 units to 3000+rpm, more decreasing of that value related to the acceleration should indicate that the air beyond the filter is less than required. AAT(ambient temp) -only Eu3/15-16P engines = real ambient temp on thermometer MAP(manifold absoolute prssure) = with AAP at idle growing to 230 at full load IAT(inlet air temp) = AAT + 10 to 30 depending on outside temp, engine coolant temp and boost(measured with coolant gauge at middle)...also it can be much higher if non-cooled EGR is still fitted COOLANT TEMP = 70 - 115 gauge stays at the midddle, the gauge will go to red zone only at 120 and the electric cooling(aircon) fan kicks in at 110 and stops at 105 FUEL TEMP = around 10 less than coolant temp THROTTLE ACCEL. WAY 1 - about 0.3V with the pedal released, about 4.7V with pedal to the maximum position ACCEL. WAY 2 - about 4.7V with the pedal released, about 0.3V with pedal to the maximum position ACCEL. WAY 3 – this track must have values very near to the second track.(only 15P-16P engines) ACCEL. SUPPLY – this value must stay between 4.9 a 5.1 IDLE SPEED = 750rpm" Hope this helps. |

I have the same error codes Aircon and autogearbox.
