Code Po606 - manual desiel cruze power loss, stalling esc & Tc control warning light

Edit: Resolved at this stage, see last comment for info. Hopefully it holds up.


Hey

My JG cruze 2.0 desiel started having an issue about a year ago.
The main symptom is generally with accelation the power drops dramatically almost jerking the car followed by esc and traction control lights going on, at times the check engine light will go on also.

Typically, i'd be driving along then accelerate to overtake or just pull away from a traffic light when the power drops out and I cannot accelerate adequately again until I restart/clear the codes.

Every now and then the engine will stall completely after this happens. Usually I can clear the issue by restarting.restarting the car a few times. This happens almost every time I accelerate aggressively now.

I've taken the car to the dealer several times each time they cannot find a fault, on one occasion they charged an outrageous amount for "gluing a wire" which did not resolve the problem.

I've scanned it with an obd app and the only code I get is P0606.

Has anyone had any issues like this and have any ideas where I cN begin to troubleshoot?

Thanks.

I'm pretty sure P0606 is just a general 'something is wrong' code. Least for the North American Cruze.

Let me just ask some basic info. What year? Have you tuned it? When did you buy it? etc..

2011 model just ran out of warranty when the issue started.
It hasn't been tuned and always logbook serviced.

It's got 120,000km on the clock and I drive it daily.


What baffles me is how Holden service department cannot identify and issue. I've had a mechanic scan it for codes and all he came across was the P0606 as I did.

So far I've tried to clean the throttle plate with cleaner as instructed as I thought it may be getting stuck, this didn't seem to solve the problem.

I'm now looking at checking the throttle position sensor but basically fishing in the dark here with where to begin with troubleshooting.

You need to find a shop that understands this engine and knows proper troubleshooting procedures. Any number of things could be causing what you describe. Paying a good shop 2-3 hours labor to properly troubleshoot will save you a lot in the long run. also make sure they stand behind their work.

Good luck. Problems like this suck!

That seems to be the only option I'm left with. I would have thought taking it to the authorised dealer/workshop where it was bought from and serviced that I would be able to get good service from them. Clearly not. I've just gone through the majority of the elctornic connection in the front end of the car and cleaned/checked them with no improvement.

Problem with that code though, is it doesn't really tell you anything. I'm not really sure how the Holden Cruze works, but the American Cruze's ECM directly drives the injectors, so it would make sense for it to fail when the ECM is under load.

Sooo I would try.
1. Checking the wiring harness on the ECM.
2. Get a fresh firmware flash from the dealer.
3. Get a whole new ECM and wiring harness.

The ECM is just plug and play, but replacing the harness is not fun.

And if you can, monitor the ECM Voltage with a scanner or something. May reveal something interesting.

I've fiddle with the wiring harness on the accelerator and brake pedals, haven't had this issue since then. Fingers crossed it was just a loose contact here or one of the contacts I cleaned earlier finally resolved the issue.
