Where is the Intake air temperature sensor located?

Hi,

To the best of my knowledge, they didn't use an IAT in 1999. Is there a specific code you are getting? Could it be the mass airflow sensor? ECT (engine coolant temperature sensor)?

Let me know.

Joe

P1113.

Hi,

That code is related to the outer/outside temperature sensor mounted in the driver's side exterior mirror.

Are you having drivability issues with the vehicles?

Joe

Rough idling when going past 30 MPH.

Plus my digital speedometer is frozen and doesn't show the numbers alongside the digital warning text box, it only lights up but doesn't show no texts or anything. could it be a blown fuse maybe?

The speedometer could be related to a vehicle speed sensor and the rough idle could be nearly anything. For example, low or high fuel pressure, an engine vacuum leak, or simply in need of a tune-up could cause the rough idle.

What I recommend is to have the can-bus scanned. It requires a scan tool that can communicate with all modules. Here is a quick video showing how it's done:

If you look below at the two pics attached, they show the can-bus system. Basically, all the modules/computers are tied together via a couple of wires. By performing this type of scan, it should identify any codes present regardless of the module. Hopefully, this will point us in the right direction.

Let me know if this is something you can have done.

Take care,

Joe

Hi Kavin Thomson,

We can help with that. first tell me how it started, have you performed any repairs recent?
for the code p1113 air temperature there are two of them in the lower front It's the one that should be fixed in the RH side of the engine splash guard it is often not and has fallen down and got damaged.
take a picture of digital speedometer.
explain about rough idle how did it start?
Let us know what happens and please upload pictures or videos of the problem.
I am glad to help you, If there is anything else we can help you with please contact us again. Thank you for choosing 2CarPros.

i will try to get you a picture and send it.

see link to understand what you are looking for this code is air temperature sensor.

This is how the engine sound.

Hi,

I'm not sure if you upload something for us to hear, but nothing came through. Could you try again?
