I can't believe the successor to the E-Type doesn't have an oil pressure gauge and I have to admit it is really driving me nuts not knowing what my oil pressure is. Kind of diminishes me as a car guy somehow. I have heard rumors of an app that will give us an oil pressure reading, is this true?

 

Nope. The F-Type has no oil pressure sending unit. The low oil pressure warning message is apparently derived. Our indicator of good oil pressure is a lack of smoke and it is 100% reliable.

 

Yep, no sending unit, just a message that says "warning - oil pressure low".
Per the Workshop Manual a couple of special tools are needed to check/test/measure the oil pressure, see attached PDF:

 

 

Can some please elaborate on what's the oil pressure shows? & why it's important to see/know?
Thanks,

 

 

Maybe, maybe not. You might need the special pressure reader too as well - 303-871 - or else it's a fairly generic screw on fitting and a much more common (and cheaper!) reader will fit and work.
We need a JLR tech to "borrow" these special tools and figure out what works and what doesn't, is it doable, can the reading be sent to the OBD2 port and/or some other data reader (eg the Torque app), and at what cost etc etc.
My guess is that like most things JLR it could be done but the cost/benefit ratio would be through the roof.

 

In the simplest sense, good pressure indicates a few things:
* you have enough oil to create flow through the pump
* you have a pump strong enough to suck oil from the sump and pump it high enough to lubricate the highest parts of the engine
* there is not enough sludge build up to impede internal oil flow
* high oil pressure may also indicate poor flow from cold oil, a partial blockage or overfill, or most often, a bad sending unit or regulator/relief valve

Very low or zero oil pressure is cause to immediately shut off the engine to avoid engine damage or impending seizure.

All that said, a lot of modern cars have more of a 1/0 sensor than a pressure gauge, to build cars as cheaply as possible. The F-Type cleverly derives that 1/0 from other sensors, presumably to save even more money.

 

How is it derived? What are the measured values that are used to calculate "low oil pressure"?

 

Would you be satisfied with a measurement of the real-time Oil Level in the sump and even a calculated volume in Litres, in your Torque Pro App?

And also temperatures via Torque App for Engine Oil, Transmission Oil, E-Diff Oil?

If so, we might have something for you very soon...

 

What is this Torque Pro of which you speak? I am intrigued.

 

TorquePro is the $5? (I forget now, but its cheap) version of the free Torque phone app. It connects to most if not all bluetooth OBD2 readers. In theory, and in every other car, you leave your bluetooth dongle on the OBD2 plug under the dash and it transmits everthing the ECU knows to the phone app. Then you can diagnose codes, reset check engine lights, and what we are talking about here, display info using prest or customized gauges and gauge sets.

Its really no different than what new cars do to create their primary digital gauge clusters and display options.

The problem is that many F-Types will shut down if you attach an OBD2 reader to the car's port. No one seems to know exactly why. Mine did and the dealer had no clue how to fix it, but covered the $3200 bill under warranty which was probably padded by $3100, since they did nothing but load the wrong ECU software, ruining the exaust note until I taught them how to fix it.

So my $11 reader works great with my other cars, but is useless with my Jags.

Dont get too exited about the performance mapping shown below, it doesn't work at all because its dependent on phone calculations on slightly delayed data and manually input weight data. The performance timers are worthless too. I says I make something like 1200hp in my SUV.

 

@ Cambo - And what would be your choice of dongle for the OBD port that doesn't stuff the ECU shut down procedure? I'm trying to gauge which type/model to get.
If you don't want to hijack the thread as I have done...I'm here asking the question:

Speaking of OFF TOPIC...

I found it difficult to fathom why an ENGLISH car wouldn't be equipped with a Voltmeter!
(Not that I've felt the need for one on the Jaguar, yet, myself.)

 

Well, if those old beliefs still applied, the voltmeter wouldn't work anyway! Most of the electricals probably come from elsewhere in the EU these days ....

Hey Lance, you're doing software development too?
