Repair Mistakes & Blunders
Repair Mistakes & Blunders

In the summer of 2002, a good friend of mine purchased a 1993 Toyota pickup 4WD that was a little rougher for the wear. Being a somewhat typical teenager, he focused more on the truck's aesthetics before focusing on reliability concerns. He chose a handmade pipe bumper, secondhand larger off-road wheels and tires, body lift and any other reasonably cheap modification to help realize his budget-minded dreams of what the truck should look like.

One day he calls me and tells me he has a bad CV joint on the front driver side. He can tell by the location the sound is coming from. We worked for hours (still rookie mechanics at this time) that evening trying to remove the axle, with little luck. While taking a breather, I leaned on the front of the truck and heard a squeak! He turned his head and asked me to do it again.

As it turns out, we did not need to change the CV joint at all. In his hurried application of the homemade front bumper, he did not use any lock washers! The squeak was from the bumper having loosened itself during normal driving for the last couple of weeks. I hurriedly applied the lock washers while loudly condemning his decision to skip said item. We finished the CV joint replacement the next morning and drove around the block to confirm the fix.

I now make sure I replicate problems and verify the source before jumping headlong into a repair.

Automotive Trivia

How did Mopar get its name?

A. Moparsetti Tooling was founded in 1912. In 1923, Walter Chrysler purchased this manufacturer of engine parts and shortened its name to Mopar.

B. Chrysler Corp. derived Mopar from the words MOtor PARts in the 1920s.

C. Don Garlits showed his passion for Detroit (Motown) and golf (par) when he named his Chrysler-powered drag racing team "Mopar" in the early 1950s. Chrysler licensed the Mopar brand in 1963 and purchased it in 1974.

Electronic Symptom or Root Problem?
Tom's Story

One of the first rules I taught my teenage daughter about OBD trouble codes is that they often indicate symptoms rather than directly point out the root problem. An oxygen sensor trouble code might be the best example of this. Problems with a fuel or emission system part upstream can lead to an oxygen sensor detecting out-of-spec oxygen levels in the exhaust downstream.

The meaning of a trouble code is even trickier to decipher if it is caused by an unrelated part with an electrical problem that just happens to be connected to the same computer. For example, a broken power steering system pressure sensor might cause an EVAP leak trouble code. Hydraulic pressure in the power steering system has nothing to do with gasoline vapor pressure in the EVAP system, but both the power steering system pressure sensor and the fuel pressure sensor are connected to the same powertrain control module (PCM).

A PCM typically provides a 5 volt or 12 volt reference voltage (VREF) to a sensor and then watches the signal voltage from the sensor change as the pressure, temperature or whatever the sensor is measuring changes. If a sensor breaks and shorts the CPM's VREF to ground, then that could influence the VREF for an unrelated sensor and generate a misleading OBD trouble code. Hopefully, there would also be an OBD trouble code for the sensor that is actually broken, but there might not be.

It is hard to predict how a computer comprised of sensitive electronics and complex software will react when a component connected to it goes bad. I have a small fan on my desk that is powered by 5 volts from a USB port on my desktop computer. If the motor in the fan were to short out or seize up, then the keyboard connected to the neighboring USB port might stop working, or I might see some error message gibberish on the computer's monitor. With my desktop computer, the best strategy would be to unplug things from the USB ports one by one until eventually discovering that unplugging the fan solved my computer's problems. Similarly with a car's computer, sometimes the best strategy is to disconnect sensors one by one until the problem goes away. Simultaneously inspect connectors and wiring for damage that might be causing the CPM's VREF problem.

My daughter's 2005 Mustang and my neighbor's 2010 Toyota Camry have Power Steering Pressure Sensors, but not every late-model car does. Some engines have EGR Pressure Feedback (DPFE) Sensors, but others do not. Look up your vehicle in the catalog to see its specific sensors. You will be better prepared if confusing OBD trouble codes ever indicate there might be a VREF problem. Plus, it is always good fun to explore all the cool parts available for your favorite ride(s)!

Justin's 1983 TVR Tasmin
Justin's 1983 TVR Tasmin

When I purchased this 1983 TVR Tasmin about two years ago, it was in a sad state of neglect. It was barely running and only somewhat driveable. But since then, it has transformed into a safe and reliable "go-cart" for adults that is incredibly fun to drive, especially on curvy back roads and cloverleaf interchanges.

Only about 1,400 Tasmins were imported into the US from the UK between 1983 and 1988, making this a fairly rare car. Most people who strike up a conversion with me about the car have never seen or heard of a TVR, typically assuming it is a Triumph. Fortunately, TVR made use of quite a few borrowed components like a German Ford for the V6 engine, drivetrain and front suspension, Jaguar for the differential and rear brakes, and British Leyland for a bunch of other bits and pieces. The Tasmin also has a fiberglass body, a tubular space frame steel chassis and four speed manual transmission. Yeah, it is a mutt. But with the RockAuto catalog for cross referencing, vehicular forensics and a willingness to modify, parts like gaskets, seals, filters and numerous other odds and ends were not too difficult to find. Nothing is terribly exotic or expensive, so this fun-to-drive car is reasonably cheap and easy to maintain.

Thanks for the great prices and service!
Justin in Kentucky
