P1113 Port Deactivation Position Sensor Circuit High Voltage . (as per TIS) there are 2 possible codes one for hi volts and one for lo volts, check all your wiring and the connector on the B1_Y21B Sensor - Twinport Position
Wiring harness connector (underneath the inlet manifold)
P1113 code Vauxhall, I have this as the Port Deactivation Position Sensor.
This is a 3 pin sensor mounted to the inlet manifold twinport rail so the ECU can determine the flaps position.
The sensor is tucked up under the manifold and is a little tricky to get to.
It is also essentially the same sensor as the TPS used in older pre-electronic throttle control Vauxhalls such as single point injection Astra-F and Corsa-B models.
Not had one fail yet, but of course it could be At Fault.
I have seen the wiring for it chafed through on the actuating rail from poor LPG installations, including the standard Vauxhall conversion! If fitted.
I would also be checking for seized/worn flaps or rail disconnection.
Incidentally, the lower inlet manifold section (incorporating flaps) comes with a pre-installed sensor.
The sensor is mounted at the opposite end of the manifold to the actuating solenoid but it is not clearly marked.
When ordering don't be surprised that it is a complete manifold that they offer you, complete with everything. Not sure of price but I think it's around £80.00.
where can i find the colour code for my 1997 vauxhall astra mk 3
The fault codes of po1120 Vauxhall Astra are 1614 and 1616 with B3055 in the CIM module.
code 82
The paint code for the Vauxhall Astra should be on a sticker on the driver's side door frame. The code for the paint is the code that the company uses. It is not a universal code for all vehicle manufacturers.
In means it needs a service
I Have a Astra Mark 4 vr500 radio please can you tell me how to entre the code Type your answer here...
just under the bonnet near the grill
P1230
Trouble code P1113 means: HO2S 1 Bank 1 Heater Resistance Too High
Although it may be entirely dependent on the exact model of the Vauxhall Astra most forums point to error code 22 as a right front sidelight failure which can be easily resolved by simply replacing the faulty light.
Code P1112 on a Vauxhall Astra typically indicates an issue with the intake air temperature sensor or its circuit. This may involve a faulty sensor, poor wiring connections, or issues within the engine control unit. It can lead to performance problems, such as reduced power or increased fuel consumption. Diagnosing the specific cause requires checking the sensor and its connections for faults or damage.
