Thought I'd bring a bit of closure to this topic: -

After getting passed about between independent mechanics and the dealer where I bought the car, I ended up going to the main Lexus dealer in Belfast who diagnosed it as a faulty MAP sensor.

Yes, this car does indeed have both the MAP and MAF sensors, the one @200h identified is correct. Lexus wanted £230 for the replacement sensor. I got a used one on eBay for £25, installed in 2 minutes and cleared the codes using a simple obd scanner.

Job jobbed.

No luck with cleaning the MAF, will try replacing it.

See attached the fault codes

Generally the car would have one or the other and it would be MAF in our case of IS300H

 

Thanks @Andrew888, I did read that but was confused by the description on the fault code that suggested it was a MAP sensor.

I'll give the MAF a clean and see how I get on, cheers.

Hi Alan

i have just had a look on jp-carparts and found this exploded view

https://jp-carparts.com/lexus/partlist.php?maker=lexus&type=242130&cartype=9&fig=8404

i think it is item 89421 SENSOR ASSY, VACUUM (FOR E.F.I.)

as this is the only pressure switch i can see.

Thanks @200h, that looks like it might be the part alright, will have a nosey to see if it can be cleaned but I suspect it is a dud as it's showing 0v to it.

@Andrew888, that would be the MAF rather than the MAP?

Hello all

My 2016 IS300h has thrown a CEL today, reading the fault codes it indicates an issue with the map sensor.

Did a forum search but did not come across any threads, has anyone cleaned/replaced the sensor? Where exactly is it?

Thanks

Just to answer the original query - yes the badges are easy removed and the car looks much better without them imo.

I used a heat gun (hair dryer) and a rubber wheel on cordless drill to remove any residual tack.
