Z18XE in a Astra Coupe (mk4)

Got these plugs which I can't for the life of me find a home for

This comes from behind the engine

Front of engine

This comes from the loom near the throttle body

Error code on the car read:


P0530 - A/C Refrigerant Pressure Sensor Circuit Open
(04) - Present

P1481 - Fan Relay 1 Signal Low / Open Circuit
(04) - Present

P1482 - Fan Relay 2 Signal Low / Open Circuit
(04) - Present

P1483 - <Unknown DTC>
(04) - Present

P1110 - Variable Intake Manifold Open Circuit
(04) - Present

P1555 - Throttle Position Sensor (TPS) Load Signal not Plausible with Engine Load
(00) - Not present

P0170 - Lean Exhaust
(02) - Present



Car wasn't running at the time and I've got a zlet fan on the front so I think that explains the spare plug at the front and the first three error codes. The P1110 must be the plugs near the manifold ? but I can't find anywhere to plug them in which really puzzles me. When the car runs (which is does), it doesn't idle properly and it failed on emissions on MOT so I think this is all related but as mentioned wtf do they plug in

I'd say the one by the TB is the TPS, judging by the codes. That would be my guess anyway!

The 3nd one goes to the right hand side of the inlet manifold. Look under the ecu you should be able to see It it's for the vacc inlet valve thing can't remenber the real name for it.

This is of the third plug

Its using the same loom that goes to the throttle body.

The second plug that looks exactly the same is coming from the back of the car. I had a feel/look around the manifold and I couldnt see anything to plug it into :/ Will have to double check.

Here you go bud this is the one in your 3nd pic witch goes behind the inlet. Few pics i tuck for you of my car. This plug should also have a black earth wire witch goes on the 10mm bold on the ECU (your see this in my pic).
