This is on a 2010 2.2 115PS Euro IV engine.
I have serviced the van recently (oil and all filters replaced) and replaced my SCV and PRV (both from PF Jones, so not cheapo Chinese copies off e-bay).
Pump learn went straight through, Pilot learn took three attempts but now has completed successfully as well.
The only DTC during this was for the glow plug circuit (the fuse has blown so that will be why).
IDS informs me that the PCM software is out of date and suggests I update it. When I went to do this though it will not start the process as it says the "battery is low".
I charged the front battery overnight (both were replaced last month with 110 Yuasa batteries, pretty sure they are OK) and connected the charger whilst attempting the update but have the same issue.
Did a self test and now have the glow plug DTC and a new one "P2226 - Barometric Pressure Circuit" it says there is 0 volts.
Ran the Datalogger on IDS and confirmed that battery voltage is 12.9 volts, but BARO sensor is indeed 0 volts.
When engine is running battery voltage is around 13.5 volts, BARO sensor stays at 0 volts.
The "BARO pressure" logging gives a reading (about 5 kpa from memory), so seems to be doing something.
I haven't bothered replacing the glow plug fuse yet as I suspect it will blow striaght away due to a dodgy glow plug and will wait until I've replaced the glow plugs with the new ones I've got on order.
SO, finally getting to a question, where is this Barometric Pressure Sensor so I can check it and the cables to it?
Van seems to be running fine, but knowing that the DTC is there and the PCM software is out of date will no doubt bug me until I fix it.
