What the P0272 code means. This code means that the PCM (Powertrain Control Module) has identified that the reference voltage in cylinder #4’s fuel injector is out of range.
What causes P0272 code?
The definition of P0272 fault code is that there is a contribution/balance problem with cylinder #4. This code would be triggered in when the engine control module detects that the acceleration rate of the crankshaft for cylinder 4 was less than a calibrated amount.
What does cylinder contribution balance mean?
The P0263 fault code can be described as cylinder 1 contribution/balance fault. This code would indicate that the engine control module has detected the cylinder number 1 having low contribution to the running of the engine, low power.

How do you read a cylinder contribution test?
Zitat von Youtube: So you can see down at the bottom left-hand corner of the screen the different cylinders and you can see they're all on. So what we do is use the up or down arrow to pick a cylinder and click confirm.
How does a cylinder balance test work?
To conduct the test, a spark plug wire from the spark plug has to be disconnected and grounded. The change in engine speed with the cylinder disconnected is the amount of drop caused by that cylinder. The test is continued by disconnecting the wire to each cylinder, one at a time, and recording the change.
How do you read a power balance?
Zitat von Youtube: Three is at forty five percent or so and two and seven and four are all right around what you call a zero line.
