Lambda is fine no boost leak. It's a weird one this.

How do you know there are no leaks?

[andre200sxs14]

He said he's had it all checked and no leaking as he's has fixed the boost leak.

Coolant Temp Sensor. It's located in front of Injector 1. Replace it with a genuine Nissan one! Don't bother with any other brand like Facet.

Left is genuine. Right is a Facet one that didn't work n sent me on a wild goose chase for months to check the rest of the stuff u have said it's not. Also u can see where it's located at the front. U can get to it quite easily by taking a couple of plugs off n maybe a small hose.

My sensor was telling my car that it was -4°C

Hopefully u get it sorted. Let us know how u get on.
