A Few Simple Steps To Find What Was Causing Fault Code P006A On This Ford Ranger.

This Ford Ranger came into the garage with its EML (engine management light) on and in limp home mode for us to diagnose.

First we carried out a full diagnostic scan of its control modules to see what fault codes were stored.

The first code that we were interested in was P006A – Correlation between MAF (mass air flow) and MAP (manifold absolute pressure) sensors.

We checked the live data to see if the sensors were giving any readings and if they were did they seem right?

Both sensors were reading but the MAP sensors seemed a bit low compared to the MAF sensor.

Next we checked for any obvious splits or leaks in the intake and boost pipes between these sensors.

Once we were happy with the pipework we decided to carry out a smoke test on the intake system to check for leaks we could not see.

Disconnect the pipe to the inlet manifold and fit a blanking plug, then fit the smoke tester end to the pipe from the air box.

It soon became apparent there was a leak from the intercooler as we could see smoke coming from the fins at the front of the cooler.

Ford Ranger Air Leak?

After removing the top cover and looking between the intercooler and the radiator we could see the large split in the intercooler bellowing smoke out.

We needed to remove the front grill and slide the front bumper forward to access the bolts to remove the intercooler.

When the intercooler was removed we could see quite clearly that the cooler had split wide open.

We replaced the cooler, re-checked the live data and finally road tested the Ranger and it was back to full power.

2019 Ford Ranger 3.2 Low Oil Pressure Light On After Service

We recently came across a problem in the Garage which we have not come across before, which was the ‘Low Oil Pressure’ warning light coming on after replacing the Oil and Filter on a 2019 Ford Ranger 3.2.

After searching on a couple of the Motor Trade platforms we use it seemed that we were not the first to come across this problem, but we spoke to our local Ford Dealer and they said they knew nothing about it.

There was apparently a technical bulletin which had gone out to dealers saying that if the oil and filter change was not completed within fifteen minutes this problem would occur due to the oil pump draining and not being able to re-bleed itself.

Personally we believe this is a poor design, when we drain the old oil from your car we want to remove as much of the old oil as possible (obviously some oil will stay in certain places of the engine) allowing the new oil not to be diluted with it.

In this particular case the only way we could bleed the oil pump was to flood it, we added five litres more oil than specified to bring the level inside the sump up to the bottom of the oil pump meaning it didn’t have to pull the oil up but just push it.

Once we had got the oil pressure up we drained off the extra five litres of oil, road tested the car and then re-checked the level.
