Vauxhall Opel Zafira air intake sensor problems

In this video, I take you through the air intake sensor. A quick video to give the DIYer somewhere tho start.

Your video was perfect. Helped a lot, my car now drives as it should.

[@drivewaydiyer6504]

Great news, Glad you got your car fixed.👍👍👍

[@jacko2815]

What issues was you having?

[@thornwarbler]

Thanks for your time mate. Its appreciated

[@drivewaydiyer6504]

Thanks for watching👍

[@Litesnip2022]

Am I correct in saying when then engine is running the temperature of the sensor should read a couple degrees higher than the outside temperature?

[@drivewaydiyer6504]

You have to take into account of all the variables of heat and where it’s coming from. The car will always be hotter than ambient temp. I suppose when the car is cold and no additional heat, it would read the same as outside. Live data is always important from cold to hot, to verify its reading accurate from cold to hot.

Hi, my code on my vectra C is p2279 and it says its an air intake sensor, would this be the sensor before the airbox . I have watched a few videos and they all seem to be a bit vague.

[@drivewaydiyer6504]

This code is for disparity in what sensor is reading and what is being read at the manifold. Might he worth checking for air leaks. Get some live data on the sensor, to make sure it’s reading correctly. You don’t want to swap it out if it’s reading ok.

[@davidhorvath1212]

Hi mate thanks for the video, i have a zafira 2007 and the revs keeps going up and down while stationary so the car is idling a little bit . Been told it could be the air intake sensor , do you think i should change it? Engine light keeps coming on and off

[@drivewaydiyer6504]

Well firstly I’d try cleaning it, but there’s lots of reasons your car is surging, could be a vacuum leak , could be egr. Try unplugging the sensor to see if there’s any change, in performance. Do a pedal test, to see if there’s any related codes.

[@MohammedYousuf-nv6zp]

Got same problem changed the sensor and wires look okay ,Any idea what else ?runs fine just engine light still on

[@drivewaydiyer6504]

Did you erase the code . Is there a leak in the duct, have you tested the wiring? It has a 5volt biased reading. If you disconnect it , it and bridge the wires, there will be 5 volts.

[@gazzarooney2157]

Hi. My sensor is ok but one of the wires has snapped inside the connector block. How easy is it to rewire or replace the connector block?

[@drivewaydiyer6504]

I’d be tempted to get another connector from the scrapyard and crimp it or solder it. Depends on your ability.

[@gazzarooney2157]

@@drivewaydiyer6504 nice one. That sounds like a plan. Thanks Very much,😁

[@MH-zs5vt]

There is code P0443 (evaporative Emission system purge control valve circuit) on my zafira b 2013 patrol, any idea please

[@drivewaydiyer6504]

Probably the selonoid or wiring issue. Check connections and wiring integrity.

[@jacko2815]

Any idea what my issie could be. Wjen i remoge the disptick can feel the engine sucking in. Have taken kff the rocker cover head fitted new one with new PCv valve. Also idle was up and diwn lots i cleaned throttle bodh now steady idle just high. Over 1k

[@drivewaydiyer6504]

Have you done a pedal test, may give you an indication, possibly an egr issue or vacuum leak. The fact you clean the throttle body and it improved it , even though that’s a high idle. I suspect it’s something around that area. Do a pedal test first though.

[@jacko2815]

I have a 2007 toyota camry xle v6 it starts and stalls out,idles sounds like it's about to back fire drives slow and shows these codes is that most definitely my intake air temperature censor

[@drivewaydiyer6504]

Check connections, make sure there’s supply to the sensor. Very much sounds like there’s a sensor issue.

[@broadsworddannyboy5057]

What if fault code is po171 air intake lean ??? Any suggestions?

[@drivewaydiyer6504]

Air vacuum leak, egr valve blocked

[@yeshuaisthesonofmantheking4065]

I have a crank start, getting this code aswell

[@drivewaydiyer6504]

If that’s the only code you’re getting, I suspect it will be that, clean the connector and the sensor. Probably worth changing it out. Can you access live data? See what temperature it’s reading?

[@davidjohnrobinson2887]

Hi. I have a 09 zafira petrol 1.6 (don"t ask me why) but i find i am cleaning the little MAF quite often, because of a lean code, works for a while then, neads cleaning again. Would like you"re thoughts on this. Thanks.

[@drivewaydiyer6504]

Just out of interest, do you live in a dusty area?

[@davidjohnrobinson2887]

No not dusty here. It can throw a code on damp days or dry. Filter pretty new also. Think i"ll get a spare sensor incase it does fail. The car drives fine though when it trips an engine light. Thanks for the reply.@@drivewaydiyer6504

[@drivewaydiyer6504]

@davidjohnrobinson2887 sounds like it needs replacing. Could be breaking down and any contaminants is affecting it, more often.

[@shibbirahmed1342]

My 2014 zafira is giving me problems. When I diagnosed it came with MAP sensor, can you help?

[@drivewaydiyer6504]

You can try replacing it, are you having symptoms, poor running etc. You should get some live data. Check connection and wiring also.

[@shibbirahmed1342]

@@drivewaydiyer6504 I will check with my mechanic tomorrow and see if it works after cleaning it

[@csibi5]

Hi there. What are the symptoms of a defective sensor like that? Thx

[@drivewaydiyer6504]

Usually lack of power, poor performance.

[@csibi5]

@@drivewaydiyer6504 Thank you. I have poor performance especially around 2000 rpm, then blows out. Map, sparks, ignition module and complete exhaust system already changed. Became better but not perfect. Error code was 0170(fuel trim) but since exhaust system change it doesn't exist. What do you think maybe oxigen sensor? Today i ordered a new air intake sensor i hope it will solve my problem, 2 oxigen sensors would be expensive.

[@drivewaydiyer6504]

I think the next step, is to get some live data, on your fuel trim and see if it’s rich or lean. The fact that you changed your exhaust and it improved. Perhaps try some cataclean. EGR valves are a huge problem on these models. They get gummed up. Check for air leaks aswell, clean the throttle body, could be sticky. But live data will be your next step.

Check behind the head, under the wiring loom.

[@jojojojo3416]

Can you advise what a P0400 code could be please? Engine lights on and it's draining fuel fast. 08 vauxhall zafira. Thanks :)

[@drivewaydiyer6504]

Egr fault , probably needs a good clean. Egrs are a huge issue on Zafira’s

[@jojojojo3416]

@drivewaydiyer6504 that's what ii was originally told but it's all been replaced 4 months ago and still have the same problem

[@drivewaydiyer6504]

@@jojojojo3416 it may need cleaning internally, some people cap them off and remap. Could be other reasons like ecu, wiring, could be a faulty egr. Lots to think about.

[@notstrongmtb2577]

I have error code p0171 do you have any ideas where to start with this error.

[@drivewaydiyer6504]

Look for a vacuum leak, you may even have an egr problem. It’s running lean, so it’s getting too much air. Look around throttle body, air intake etc splits, broken pipes etc

[@drivewaydiyer6504]

If there’s no codes it may not be an issue with the sensor. Might be worth clean the the throttle body, with some carb cleaner. The valve can get a bit sticky and choked up. Try that first. Check air filters and plugs too.
