Z16 XEP DIY Fix – P1113 Vauxhall Astra repair – p1113 Opel Zafira port deactivation position sensor low voltage error

P1113 Vauxhall Astra Repair – Watch the Video below on YouTube and see just how easy it is to save your self a fortune …

P1113 is a Common fault on Vauxhall Astra H mk5 and Vauxhall Zafira B mk2 fitted with engine code Z16XEP

The problem relates to wear with the port deactivation flaps in the intake manifold

Vauxhall repair for this is complete replacement of the inlet port manifold at great cost.

The fault is detected by the engine ECU when the port sensors resting position is below 0.3 volts (due to slight wear in the linkage) This can be easily adjusted by placing a 400 to 500 Ohm resistor in the brown wire to pin 2 of the port sensor (sensor ground) this will then step up the voltage seen by the engine ECU by just a small amount, enough to be within the programmed min tolerance limit

• Min voltage resting position of port deactivation sensor is (0.3 volt)
• Max voltage resting position of port deactivation sensor is (0.5 volt)

This can be seen diagnostically in live data or with a volt meter

This signal voltage can be measured at port sensor pin 3 red/blue (ignition on engine off)

• P1113 Vauxhall Astra
• P1113 Vauxhall Zafira
• P1113 Opel Astra
• P1113 Opel Zafira

With engine code. Z16XEP

FIX Vauxhall fault code P1113

Port Deactivation Position Sensor Low Voltage error

1 Check live data from air intake port position sensor (engine off Ign on) should be between 0.3v – 0.5v

2 Disconnect wiring from port sensor, unclip from lower manifold and pull up wiring above engine

3 Cut wiring to port sensor pin 2 brown wire

4 Solder resistor between 400 – 500 Ohms in between brown wires

5 Re insulate wiring and reconnect wiring to port sensor

6 Re check port sensor voltage is between 0.3v – 0.5v ideal is 0.4v (Ign on engine off)

JOB DONE! 👍
