SOURCE: WHAT DOES A CODE P1105 MEAN

it is showing that that code is an alternator fault. make sure you have good connections on your battery cables and have your alternator checked.

SOURCE: nissan quest 1999 engine light codes P0325 &

P0325 is for the knock sensor.

P1105 is for the manifold absolute pressure sensor (MAP).

In either case diagnostic tests need to be performed to rule out faulty sensors or if something else is causing the sensors to give the computer inaccurate information.

SOURCE: i have fault codes po105,p1105,p0100,p0234,what is

The missing codes may be Saab-specific but two were found:
- P0105= MAP/BARO Circuit Malfunction - P1105 not listed - P0100 " " - P0234= Engine Overboost Condition
If in the US or Canada, check with a chain auto parts store, they may have all of the codes.
Hope that helps-

SOURCE: I took my car to get an emission and the P1105

P1105 = MAP/BARO Pressure Switch Solenoid Valve

The problem is in the map sensor circuit, it could be solenoid valve. Check the vacum line that goes to the MAP sensor.

From the B14 Factory Service Manual, has a procedure for checking the MAP/BARO solenoid valve when P1105 is tripped. It is rather complex, and you will need a volt meter, but...

1- Warm up the car and pull the vacuum hose connected to the MAP/BARO switch solenoid with the engine idling. There should be vacuum there (~ -20in Hg). If NG, replace the hose.
2- Check the vacuum hose between the Absolute Pressure Sensor and the solenoid for splits/cracks and clogging (blow through it).
3- With the engine off, disconnect the solenoid electrical connector. Turn the ignition switch on. Check the voltage between terminal 2 (brown wire) and ground. It should be 12v (battery voltage). If no voltage, check the 10a fuse #21.
4- Check Absolute Pressure Sensor. Remove the sensor with its wiring connected. (Located near the top of the firewall next to the cruise control actuator [disk-shaped on a bracket]). Remove the hose and turn the ignition on. Voltage between terminal #2 (white wire) and ground should be 3.2-4.8v. Apply a vacuum to the hose and the voltage should be 1-1.4v lower than the first reading. If NG, the sensor is bad.
5- Check the solenoid. Remove the solenoid electrical connector and hoses and check the air passage continuity by applying 12v to the connections. With 12v on, there should be continuity between the two close hose connections, and no connection between the lone connector and the double connection closest to it. With no voltage applied it should be the opposite (no continuity between the close ones, and continuity between the far one and the closest double one). If NG the solenoid is bad.

I hope this help.

Hi my Saab 2001 93 2.0 turbo convertible has lost power get into limp home mode I reset it every few weeks codes come up p1105 p1260 p1251 p 1264 what do u think is wrong ?


code p1105 refers to manifold absolute pressure(MAP) sensor, TC system-leak detected. causes ---intake leak, ---hoses There are to references to p1105 The second response is still map sensor but the causes are---TC system--mechanical fault--air leak between throttle body-TC,map sensor---TC system--exhaust blockage
code p1260 refers to throttle return spring--weak spring force. causes ---mechanical fault,--,throttle control unit
code p1264 refers to throttle valve opening-accelerator released causes ---throttle control unit---mechanical fault
