Oil Pressure Switch Causing Lean Code?

Posted on November 1, 2018 by Dan

This is going to be a long and technical post, but if you want to learn about car engines, this should be a good read even for the non-technician. A Honda Odyssey came into the shop with the check engine light on. I scanned the codes and found two seemingly unrelated codes. When you have multiple codes you have to decide if you can diagnose both at once or if you have to fix one before the other. The two codes that I had were P0171 Bank 1 Fuel System Too Lean and P3400 Valve Pause System Stuck Off Bank 1. Besides both being on Bank 1 of the engine, I wasn’t sure how they could be caused by the same problem.

Throwback: Old Engines

Posted on October 25, 2018 by Dan

Going back a few years for this one for some engines you don’t get to see every day.

While I was in school, an older friend invited me to her husband’s engine shop. It was pretty cool seeing the shop, all the specialized equipment, and the engines they were working on.

Swollen Lug Nuts

Posted on October 22, 2018 by Dan

Sometimes even a simple part can have a bad design that makes a job take way longer than it should. One example is a certain design of lug nut. Lug nuts have a simple job, all they have to do is hold the wheels on. They’re usually chromed so they don’t rust as quickly.

Rusted Exhaust Studs

Posted on October 15, 2018 by Dan

A somewhat common problem on Hondas as they get older is an exhaust leak at the joint between the converter and tailpipe. This happens when the nuts and studs holding it together rust away and let it loosen.

The Wrong Way to Repair Brake Lines

Posted on October 11, 2018 by Dan

When brake lines start leaking, they need to be replaced. Usually they leak from rust, and when they happens, either the whole line needs to be replaced, or just a section of it. The right way to do it is with either an entire new line, or connect a new section to an original section using proper flares and a union.

Posted on October 1, 2018 by Dan

Recently we had a customer come in because they checked their oil and didn’t see anything on the dipstick, so they added oil. Checked again, still nothing, so they added more. And again.

Broken Ball Joint

Posted on September 27, 2018 by Dan

Ball joints are a crucial part of a car’s suspension. They’re attached to the steering knuckle or spindle, sometimes one at the top, as well as one at the bottom, and allow all the different directions of movement needed in those locations. If a ball joint breaks, that’s a big problem.
