P017227 Mixture cylinder bank 1 too rich, Signal charge rate above permissible limit value.
P017222 Mixture cylinder 1 too rich. Signal amplitude greater than maximun amplitude.
P010664 Intake manifold pressure sensor malfunction.

Owner describe there is surge/jerk on sudden acceleration. Please advise what to be check.
Please help.

Air mass sensor and Intake manifold pressure sensor
Inspection method confirmed by wis

This model don't use air mass sensor, only pressure sensors. The car act normal after clearing fault code, only reappear after few days. Are these fault code anything to do with primary oxygen sensor ?
Thanks.

there is also the case of o2sensor
I think to be in a different place.
There is a case in which you issue this code in misfire
Also requires inspection of the plug-and-coil:fuel regulator

[malguy]

I will replace the intake manifold pressure sensor & test. Will report back.
Thanks.

Intake manifold sensor arrive today, will have the owner drive the car for few days & report back.

i think that is best way is following the producer on xentry

[kevinx]

Did the costumer come back yet? Did you check fuel pressure. How about the injector on cyl 1. Injector leaking or spraying too much fuel? Did you follow what Xentry said to do?

[malguy]

The owner haven't turn up. Xentry don't give any clue
I will report once have update.
Thanks.
