New Case Study: Honda Passport

The customer reported that when driving the vehicle it felt like a ‘kangaroo‘. The vehicle ran unstable and very erratic. There was no EML (Engine Management Light) on, however a scan tool was connected to the vehicle to see if there was any data or pending codes stored to give a quick idea what could be causing the problem. As we guessed by no EML there was nothing. We decided to road test the vehicle and get an idea of the customer complaint. The engine started fine, a quick blip of the throttle revealed that the engine would throttle without restriction…

Forum Question!

Here we have a a question from our forum which we feel is probably out there on many lips. It even received two responses from forum experts Autonerdz (Tom Roberts), and our very own Lee Hearnden…

Q. What are the advantages of a 4 channel scope over a 2 channel one? Just wondering exactly what you can do with a four channel that you can’t do with a two channel?

Answer 1: To be fair it depends on you as a person and how you work. My honest answer based upon my usage is 4 channels is the way to go. If you think of a customer who brings a car in for lack of power, let’s say a Common Rail Diesel engine with no fault codes present, where do you go? Well you could connect the scope as follows:

  • Channel A: Digital MAF
  • Channel B: Fuel Rail Pressure
  • Channel C: Boost Pressure Sensor
  • Channel D: IMV Valve

In one simple wide open throttle (WOT) test you get a picture of the Intake/Fuel system which potentially allows you to see all the parameters which could cause loss of power in one hit. Now we know these may not be the issue all the time, but its a quick way of seeing what’s going on. With 2 channels you would probably want to run a combination of multiple tests which takes longer and potentially making the job last longer then it needs to. In reference to our customers, most customers who purchase a 2–Channel Scope always come back for the 4–Channel model and by doing this costs a lot more long term, so if you can budget the 4423 or one of the 4 Channel kits then this really is the way to go.

Answer 2: Let’s say you wanted to check the sync on a Ford electronic distributorless ignition System (EDIS) cam sensor. Maybe there was recent work done and now there is a hesitation with no codes. You know that this can be a result of the cam sensor being installed 180 degrees out of phase. You also know that the powertrain control module (PCM) will not know there is a problem and the cam and crank relationship will be identical to one installed correctly. So…with a third channel you can simply observe the secondary with the cam and crank to immediately know where the engine is in the cycle. Sure you can get it done with two channels but more steps are needed. Almost without exception, customers that get a two channel later wish they had the four channel when they discover the possibilities.

Best of the Web

Here we have another video by Motor Age. This video, titled “Scoping Out Drivability: The Trainer video series (Nov 2011)” is presented by Peter Meier. The subject this month is quite simply to show just how much information you can capture, using a digital storage oscilloscope (DSO).

Diagnosing drivability problems on today’s cars presents several challenges to technicians. Many engine designs are unforgiving of even minor flaws, and are quick to let their driver’s know they aren’t happy by displaying various signs of poor running, poor performance, and the turning on of the engine management light. Finding these minor discrepancies takes a trained eye, a little patience, and the right equipment. One such piece of equipment is the DSO. This modern version of the old big–box engine analyzers many of us grew up with is capable of much more than simply tracing secondary ignition patterns. With the addition of a few accessories, it becomes a powerful and time saving tool that can help you find those minor discrepancies when other diagnostic techniques will not. Join technical editor Pete Meier as he shares some of those techniques in this month’s edition of “The Trainer”.
