Hello all,

Just wondering if anyone has had experience with the fault code P062D "Injector Control Module, bank 1 - performance problem"?

The car had been parked up for 4 days, then just wouldn't start. The issue doesn't seem to be battery related as its showing sufficient voltage, with multiple starts being attempted by an RAC patrol. There is a clicking noise coming from the glovebox area when a start is attempted, for a few seconds, and the glow plugs light etc are all showing as per normal on the dashboard.

The engine just doesn't tick over and the check engine light then appears along with reduced engine performance.

The OBD is only showing one fault code; P062D "Injector Control Module, bank 1 - performance problem".

The car was recovered to a garage and has started normally displaying no faults approximately 5 times, until the 6th when the same fault code returned.

Kind Regards,

Mark

P-062D00

The DTC is stored if the ECM detects that injection time is incorrect.

Possible source:

Loose connections.
Contact resistance and oxidisation in the terminals.
Open-circuit in signal cable (+).
Open-circuit in signal cable (-).
Damaged injector.

The above is from VIDA. Check appropriate fuses, connectors and wiring for obvious faults as above. If the cause is not apparent, further investigation involves investigation of DTC frozen values, status identifiers and counters, together with communication and activation tests through VIDA and where necessary, using a breakout box.

Bottom line; if the cause of the fault isn't visually obvious it will likely require a garage with knowledge of what to do next, possibly directed by an aftermarket diagnostic package, but access to the functional descriptions and wiring diagrams etc. in VIDA would help and tend towards an independent Volvo specialist or dealer, although the latter is perhaps more likely to just keep changing parts until they either fix it or give up.

Thanks for the reply!

So the car spent a week at a local Volvo dealership and they said they could not find any faults. They even left it outside in the cold and rain, and the car looks to be continually starting first time every time!

They kindly didn’t even charge me, saying all they have done is start the car afew times each day over the week and checked for fault codes.

Having just done a couple hundred miles in it, hopefully it was just a one off…

Just an update;

So since the first post, P062D has reappeared randomly twice, with the car eventually starting after the 8th & 2nd attempt.

In addition, it’s now randomly experiencing a power loss that recovers near instantaneously, when cruising at light throttle. (Eg at 40-60mph and never whilst on cruise control, or accelerating). This is not often. EGR, DPF etc are all operating normally. My OBD shows the battery and control module voltage drop to 13.1V when this occurs, and instantly recover to 13.5-14.6V. On the worst loss of power and judder it created, it threw up the P22910 fault code. (Injector control pressure to low - engine cranking).

I took it back to the main dealer, who wanted to replace the fuel pressure rail, as the fuel pressure sensor comes up as one of the possible sources on VIDA. The fuel filter was replaced last month and I’m experiencing no difference with fuel consumption.

I’ve asked them to look into the wiring, for a loose connection / oxidation of a terminal, as described in post #2 above, due to the very intermittent nature of the problems! It’s just done just over 200 motorway miles without a single issue…!

I will update when I know more, incase any one else experiences these issues!

Hi, have same trouble, but a little worse, it starts up well on a cold one, but after a couple of minutes the speed starts to float.
I cleaned the throttle, egr, manifold, it helped for a week and everything started all over again. when the car warms up to operating temperatures, it gets better
waiting for your answer, maybe you will find the answer.
I have D4 2.0 2015 290k km

I got the car back from the Volvo dealership yesterday. The bottom line from them was “No fault found” regarding both P062D and P22910 fault codes. They checked all connections, tightened a few and cleared the DTCs. (I previously cleared them with a 3rd party app and OBD scanner).

So far the car has run fine, but time will tell again as it was an intermittent problem!
