355 1995 F355 Engine code 1112

It is a blue sensor, Ferrari part# 125769.
OEM is a BOSCH 0 280 130 026.
A Motronic 2.7 F355 has two, one for each cylinder bank.

 

This sensor is easy and cheap to come by. Different other manufacturers for sensors with the same spec help to keep the costs for it down (Maxgear, Beru, ...).
Here in Germany the compatible Maxgear 21-0124 can be bought for EUR 3,15 incl. VAT that equals USD 3,57. 1112 turns out to be a quite cheap errorcode.

It may not be too difficult to get to, but you'll probably lose a lot of coolant.

 

This is an easy fix. Nothing has to come apart. Drain some coolant from the radiators. Disconnect the wire to the sensor. Replace the sensor. Reconnect the wire. Fill with antifreeze. Shouldn't take more than an hour and the part is under $50 plus coolant.

But if it's going on and off it may be just a bad connection or broken connector.

 

2.7 has two coolant temp sensors that feed the two CPU. It also has one coolant temp sensor that feeds the instrument.

5.2 has only 1 coolant temp sensor feeding a single CPU. It also has one coolant temp sensor that feeds the instrument.

Changing that one sensor is fairly easy and if you are quick, you won't lose much coolant.

But you will never get your engine to look as shiny as Qavion's

 

The yellow circled one is the water temp "transmitter" for the cockpit gauge.

I wish it were mine It's a borrowed photo (probably Elliott's )

 

I think that’s Terry’s engine judging by the painted throttle bodies his posts and restoration threads from years back were a massive motivation for me!

I have changed one of the 2 sensors at the back of the motor once before and if you do it quickly you don’t lose much coolant at all.

Mine : )

I did notice a lot of wiring harnesses blocking access to my 5.2 sensors. Maybe it’s easier on the 2.7?

 

I would not advise changing w/o draining some coolant. I did one on my car that way and it was a mess.

 

hey Elliott, are those fuelrails original or did you some modifications on its? Your car having the connecting ports for an fuel pressure gauge which are mentioned in the wsm. My 2.7 doesn't have those

 

To this date, after owning two 355 (2.7 and 5.2), and seeing dozen more 355s, I have never figured out why the factory fitted those schreider valves at the fuel rails on some 355s, and then removed them on other 355s.

 

Yes it definitely can make a mess but it’s pretty easy to prevent a massive spill with some microfibre towels and fast hands.

 

They are original. Some models had the check valves on the rails to test fuel pressure.

 

Where is the sensor that feeds that dash dial on 2.7 348? I believe the two for the ecu are under the intake manifold in that tunnel.

I don't understand why the sensor is mounted at an angle. It's the same for the F355, but that points slightly upwards.

 

Hey all

I'm getting code 1112, Check engine 5-8

I replaced the driver's side engine temp sensor, warmed it up, burped it, drove it, code is still present

What else would this point to?

Are there only two engine temp sensors?

The reading on the dash is accurate, fans are kicking in, etc.

 

On the 355 their is also one in a rad djrivers side
Lhs for Ian and his buddies

 

Yup
Nailed it again ha ha

 

i have had both a John experience and a good one so it’s a crap shoot

 

Because they wanted to make my life a living hell for 3 decades is my only thought
