Hi All,

this morning my elec problems continued with the new [for us] omega. It's done 70 miles since the last problem. A friend at a garage put the diagnostic machine on and it's come up with the following errors

1525 Limp Home Problem Error
1526 Limp Home Adaption Error
1550 Electrical. Electr thr control power management

Any ideas of the above. My mechanic isn't sure how to resolve the above issues. Basically when the errors aren't there the car runs fine and then...

... it won't go anywhere. You can start it up but, it automatically goes into limp home mode and it won't rev above idle. If you put the car into drive, it'll jerk along at 5mph because that appears to be the speed when it's idling.

My car is a 2.2 Petrol Auto if it helps you to help me.

Thanks for your help and thoughts in advance.

How was the 70-mile-ago problem solved?

The fault codes relate to the electronic throttle control, so the problem is either in the throttle pedal position sensor or the throttle body itself.

In the first instance, check that the connectors to the above are secure and perhaps clean the contacts.

Can't help to clean out the throttle body in case it is sticking.

Getting it to a tech 2 for a look at the live data might reveal more detail.

Start by doing a full throttle body and breather clean

Sounds like a cam sensor failure to me.

If it is, only fit a genuine one from a Vx dealer, or else to problem will continue.

The problem was erased by clearing the problem codes and restarting the engine... simple fix! It was suspected that because the engine's battery died it might have been related to that. Evedently not!

So... Vauxhall Car Parts sell 'genuine' vauxhall cam sensors... does anyone know if this is a genuine replacement part [i.e. it'll fit where the original vauxhall one used to fit] of if it is actually a vuaxhall part these guys sell? Any experience of these people??

I wondered if it was the Cam sensor as doing a search before positing... this seems to be a gremlin for many potential electronic error codes but what about your thoughts on a prior post that suggest the throttle body or throttle position sensor?

Thanks for this Kevin, what about the Cam sensor... originally I thought it might be this and others seem to suspect this as well.... what are your thoughts as to why it might be the TPS rather than the Cam sensor?

Gotta read this bit:
"Any parts that are not genuine Vauxhall are indicated with an N at the end of the part no."

[Auto Addict]

Do not, repeat, DO NOT, fit any cam sensor that has not been bought from a genuine Vx dealer, or you will be wasting your money!

Just that the codes listed all point to the electronic throttle control, and symptoms suggest that this is in limp-home (not responsive to throttle). Could also be a cam sensor, but would expect some more codes, especially relating to the sensor itself. That doesn't mean that it's not, and can we be 100% sure that those codes were listed as present and not old codes stored in the ECU from a previous fault?
