P1110 - Charge Air Bypass Valve

[SaabWorld]

Performance Problems



Fault symptoms

• CHECK ENGINE.

Type of diagnosis:

- Continuous. But interrupted when fault criteria fulfilled and will not restart until next driving cycle.

Enable criteria:

- General conditions for this trouble code: Atmospheric pressure must exceed 72 kPa and the engine coolant and intake air temperatures must exceed -7 °C.

- Main relay voltage exceeding 10V. Engine speed below 3500 rpm. The inlet pressure drops rapidly by more than 3 kPa whereupon the accelerator pedal is fully released. The charge air pressure exceeds 120 kPa. The solenoid valve for the by-pass valve has been deactivated.

Fault criteria:

- Charge air pressure pulsating at 14-18 Hz with amplitude exceeding 3 kPa. Criteria must be fulfilled on two separate occasions within 600 s during the same driving cycle.

Dependents:

- P0106, P0107, P0108, P1105, P1106, P1107, P1108, P1530, P1531, P1532, P1631, P1632 and P1633.

System reaction to a fault:

- The MAP sensor is used as a substitute value.

OK report:

- Enable criteria fulfilled and amplitude below 1 kPa. Criteria must be fulfilled on three consecutive occasions during the same driving cycle.

Diagnostic help

Fault diagnosis concerns a fault in connecting control hoses, in the solenoid valve or the bypass valve.

Functions in the diagnostic tool related to the fault:

• Diagnostic status for the diagnosis.
• Activate output for bypass solenoid.

Did anyone ever resolve the issue at hand when the p1110 code was pulled? I recently purchased a 2004 9 5 aero and this code came up almost a week ago. I would like to get it fixed before I hit the road this weekend.

There are quite a few threads about the P1110 code. You may get quicker assistance when you reply to an existing thread if you think that applies to your situation as well. Just put P1110 in the search box and you'll find the threads.

I found the problem. The hose is missing from that main tube beside the oil filler cap

[photousa]

Do you have a photo of exactly the hose that was missing and where you installed the replacement? Why would that hose be missing? Did that solve your P1110 code issue?

Got the P1110 code on the way to work this morning. Searching under the hood I found a disconnected hose. Question is where does it reattach?

[NordWulf]

Where does it come from?

[writerchad]

hopefully this picture will be more clear. the tube comes from a t-joint.

Once I get back down to my building's parking garage I can check this diagram.

still couldn't find a nipple.
