Came in for quick code read 2 codes p0725 & 1335 as far as i can remember.Both codes related to rpm signal to ecu but on live data crank and pump rpm were all ok , these codes will not clearand the rev counter is inop when the mil light is on.Does the ecu calculate eng rpm from inj pump if crank sensor goes wrong and are the crank sensors similar to petrol for going wrong.Symptom are very flat uneven idle will not rev out when light on (limp home??) have rebooked later this week to investigate a bit longer.
Regards John
