Check Engine Light: P2183 and P0110

Got a CEL when I started my 2014 a couple of days ago, the codes are P2183 and P0110; as far as I could tell the car behaved normally. I reset the CEL codes earlier today with an OBDII reader and went for quick 20min ride and the CEL stayed off. Anyone else experience similar?

P0110 is a general code for a problem with the Intake Air Temperature (IAT) electrical circuit sensor sending incorrect voltage input signals to the Engine Control Unit (ECU).

P2183 is an OBD-II generic code for the engine control module (ECM) detecting the engine coolant temperature sensor (ECT) #2 is out of range and performance does not correlate with ECT sensor #1 .

Looks like you have a bad sensor.

Thanks for the reply CK!
Anyone know if the replacement of the faulty sensors be covered under the 5 year engine/drivetrain warranty?

It might be just a one time sensor glitch, a loose wire or bad ground. If it went away and does not come back, I wouldn't worry too much. If it keeps coming back, you might want to have it checked by someone with a real diagnostic machine. Throwing parts at it without knowing what the problem actually is can get expensive.

Any idea of where the sensor is located? YouTube videos send other sites say back side of engine on driver side. But it's not there on my 2015 Mazda3 skyactive. I'm only seeing sensors in these radiator and thermostat housing. My CEL is lit, I have same codes, but not sure which one to replace.

Have you tried to reset the CEL? On my 2014, after reset, as of today, it has not come on again. IIRC, there are 3 sensors involved: one near the back of the engine compartment on the passenger side, one on back of engine on driver side and the MAF (detects air temperature).

Hi. Could you help me. I have the same errors, and I want to try change the sensors. But I can't find right location for sensor NO.2. All what I found in google didn't help me. Maybe you can point arrow on a photo with mazda under hood space, and I'll try to find it again.

Forgot. I have mazda 3 sedan, iGT 2014

Thanks

In the 5 months since the reset, my CEL has not re-appeared. I also noticed that the anti-freeze level was a bit low and topping this up may also have helped with the CEL (since one of the sensor readings is of the anti-freeze temperature).

The rad Thermostat is a good preventative maint. part for a 4yr+ vehicle

I normally cancel all registered codes and retest the car before I take any action on them. There are too many causes of spurious codes to warrant taking action on a single occurance of a code registration.

Hey, got a similar issue, check engine, but only the P2183 is showing. I remember when I changed oil almost 7 month ago, they noticed my coolant level is low. Could it be a faulty sensor or I actually have to top up the engine coolant? It's 2016 mazda with 81k kms so wondering if it's time to change the coolant?

The sensor was failing, posted an update here: https://www.mazda3revolution.com/threads/cel-p2183-and-p011a-update.235841/#post-2462613
