how fix port Temperature sensor error 8.2 MAG

Hello,Please Tell me how to fix the error "port temperature sensor", beeps, but the engine temperature is normal.
Begins when you turn on the ignition.


2 temperature sensors are changed. The signal to them is normal (5v).

Your looking at exaust temps not engine temps I think. If there a 2 wire sensor, read that value when cold and put a resistor of that value across the wire

I checked and changed these two (№16)



and check #11 but this other "engine sensor error"



Where can I find another engine temperature sensor?

Your error is warning you about #11 in your parts breakdown, not exhaust manifold temp.

Get someone to scan the PCM for you. Stop throwing parts at it.

I live in a Thai village, nobody help here..

Maybe i can buy a PCM scanner on ebay or aliexpress? What is needed for this engine?

The part numbers are the exact same for the exhaust and engine cooling system so you ought to be able to use one of the new ones and give it a try..., 885342002

Since you have 2 engines, "Port" on your gauge should be meaning the left engine.

This is a really good scan tool to buy if you're going to be working on the engine yourself, http://www.rinda.com/techmatepro/index.html

Call or send them an email to confirm the correct adapter for your engine model as they have a few types nowadays such as,
2008 - Up (PCM-09 catalyst equipped) Adapter #94027....94029 CAN Network Adapter for all catalyst equipped engines, also used on many manufacturers 2008-Up engines • 94032 Mercury CAN converter Used with adapter 94029 to allow connection to 2008-Up Mercury 10-pin CAN networks

This is the last temperature sensor that I have not checked.



cost 3 $ and everything works




oh yeah, and a computer scanner will be delivered soon ...
