2008 Holden Colorado Pricing and Specs

I'm with you, Allan; I much prefer a hardcopy book I can lay out in the engine bay with me while I'm working on a car, rather than an e-book that requires an electronic device to access it.

A quick online search revealed that while the official Holden manual is, indeed, most commonly available as an electronic document, there are plenty of hardcopy workshop manuals from other companies available to buy. Another possibility would be to try a Holden service centre to see if it still sells workshop manuals for its cars. Some public libraries also keep a selection of workshop manual to borrow.

The best place to find workshop manual is a swap meet where some vendors have literally hundreds of titles to choose from. A second-hand workshop manual is not only a great form of recycling, the pages with the most greasy fingerprints will give you a good hint on the major problem areas of the vehicle.

If replacing the actual sensor doesn’t fix the problem, then you could be looking at a problem with the wiring that connects that oxygen sensor to the car’s on-board computer. Did the mechanic that changed the sensor check the condition of the wiring? This equipment all lives very close to a very hot exhaust system, so damage from that is not unknown.

There’s also a chance that the computer itself is throwing up a bogus fault code when it’s interrogated. Temporarily swapping the computer for another one is a reasonably simple way to rule this out. There’s also a chance (and it’s more common than you might imagine) that the brand new oxygen sensor you had fitted was a dud straight out of the box. This has definitely been known to happen, and it’s the first thing some experienced mechanics will think to check.

 It could be that they’ve replaced their pumps and the flow was too high for your car. Try tempering the flow next time you fill at that servo, and to be sure fill at another servo to see if it does it at other stations or it’s just related to the newly renovated one.
