Check Engine Light Tune-Up Update

Last time our 2004 Volkswagen Passat GLS 1.8L 4Motion five-speed received a new engine speed sensor (or crankshaft position sensor) and a Mass air flow (MAF) sensor.

This made our EPC light go off. Our check engine symbol turned back on. Now it is off again.

We brought the car to AutoZone or O’Reillys for a free code reading session.

Here are the codes it threw:

P0171

16706

17544

16825

16705

17519

We ordered this part which will allow us to read the codes and clear them from the computer.

Here is a tool to remove them.

Also a vacuum leak so I will check the connections and run the test and then see.

A propane torch unlit will help you find where the leak is. As the car sucks in the methane the idle goes up. I think this is the best way and is safe?

We drive our car many miles with Uber and on family road trips. We bought the car with 92,000 miles three months ago now it has 106,000 miles.

I added these hex head stainless steel screws to the air box heat shield. The old screws were Phillips head and very difficult to remove.

In 1991 The New York Times Doubted Climate Models: Exxon Not the Only One

https://niflheimmedia.wordpress.com/2016/04/01/climate-change-science/

Historical background before reading the article…
________________________

http://www.nytimes.com/1991/05/07/news/an-oceanic-indication-that-earth-s-climate-might-regulate-itself.html?pagewanted=all

The New York Times said something very interesting in 1991:

“The predictions rest largely on computerized mathematical models of the climate system that all scientists agree are crude and flawed. One of the major flaws has to do with the effect of clouds.”

http://www.sandiegouniontribune.com/sdut-sd-me-ramanathan-scripps-climate-change-2016feb24-htmlstory.html

The above article is different than the one in 1991:

“I cannot see how the planet can have a runaway greenhouse effect” given the new findings, said Dr. Veerabhadran Ramanathan, a climatologist at the Scripps Institution of Oceanography at La Jolla, Calif. With a colleague, Dr. William Collins, he presents the evidence for the thermostatic mechanism in the current issue of the British journal Nature.

Uncertainty? Did they really say that swear word?

“Another uncertainty, Dr. Heymsfield said, has to do with the source of the warming in the Ramanathan-Collins study and the source of the human-induced global warming that scientists predict. In the former, the source is sunlight and surface sea currents. In the latter, it is heat-trapping atmospheric gases.”

So I’m not cherry picking there was a little doom…

“The findings do suggest, he said, that greenhouse warming, if it is large enough, could cause the much cooler oceans outside the tropics to warm to the maximum, establishing a more or less uniform oceanic temperature throughout the world. This in itself would have profound effects on the world’s climate, he said, since it is the differences in temperature among the oceans that largely sets in motion the planetary winds that create and shape regional climate. With these differences eliminated, regional climates could be expected to change profoundly and disruptively. This may be the most significant aspect of the Ramanathan-Collins paper, said Dr. William A. Nierenberg, a geophysicist who is director emeritus of the Scripps Institution and who has expressed doubt that global warming will be as severe as some scientists have predicted. A number of feedbacks might act to limit global warming, he said. “In fact,” he said, “the average global temperature change could be almost zero” because of the many feedback mechanisms. But the operation of the mechanisms could nevertheless impose a “severe” price in terms of the regional climate changes they would cause.”

But the quote went south at the end…Also there were worse storms in the past so WTF? CO2 reduction wont save you from storms they happened in the past so they will probably happen again.

https://niflheimmedia.wordpress.com/2017/01/09/atmospheric-river-headed-for-california/

Here is what the article was about…

“At the same time, huge, tall thunderclouds formed. As they reached freezing altitudes, the tops of the clouds turned into monstrous, flat “anvils” of cirrus clouds made of ice crystals. Together, at their maximum extent, the cirrus clouds covered nearly four million square miles of the earth’s surface. Normally, cirrus clouds help trap heat in the atmosphere. But the thicker they become, the more sunlight they reflect. Eventually, said Dr. Ramanathan, “the cirrus becomes so thick and so highly reflective that it shuts off the sunlight reaching the ocean.”

This was more than enough to counterbalance the warming below, the scientists say, and the net effect was to prevent the sea surface from warming further. Once the cooling begins, they found, the tall thunderclouds and the cirrus dissipate, and the process starts again. ‘A Very Simple Effect’

So Exxon weren’t the only ones casting doubt…

2004 Volkswagen Passat 1.8L Turbo 4Motion Stationwagon: Tune-Up, EPC, Engine Light MAF

IMG_2887IMG_2884IMG_2882IMG_2880IMG_2868IMG_2867IMG_2865Last time.

In order to change the engine speed sensor remove the coolant reservoir. The bottom hose can be left attached so the reservoir doesn’t need to be drained just move it to the side.

You might not need to remove the oil filter but I did. I just put it back on and checked it a bunch of times. Should have changed the oil and replaced the filter but I had some miles left on the change.

A 10 mm socket and ratchet removed the bolt that holds the sensor in place. I cut the sensors wire since it was buried in a rats nest behind the engine. The wire is connected to a bracket on the firewall. I pulled the wire that was cut through the holders and rerouted the new wire and held it in place with zip ties.

Last time:

So I put it all back together and now the engine cranks but won’t start at all.

There are cheaper sensors but I’ve had bad luck with cheap sensors in the past… Anyone had luck with them?

The chain parts store said they couldn’t plug the car in to see whats wrong with it until the lights stay on. I don’t want to pay the money to take it to a mechanic with better diagnostic computers than autozone.

The phillips screws that hold the heat shield on are going to get replaced with hex head screws.

The mass air flow sensor is held in place with two safety torx head bolts T20 I think…

I didn’t have these so I just sprayed the whole unit with the spray after I removed it from the air box.

The air box is hard to get off. You need to unplug the electrical connection here and unclip the clamp that’s on top of the air box.

2004 Volkswagen Passat 1.8L Tune-up: Mass Air Flow MAF Sensor Cleaning, Air Filter Replacement EPC Light

Online forums are a great place to get information regarding your car. Trust but verify all the information you receive. Sometimes they have golden nuggets from experienced mechanics and enthusiasts other times they can be whirlpools of ignorance. I got some great information here:

http://www.passatworld.com/forums/b5-garage/208641-car-wont-start-epc-light-comes.html#/topics/208641

The air filter is located on the passenger side and underneath a plastic cover which is removed by pulling it off its snaps.

The battery is located under a panel close to the firewall. The cover helps keep the terminal from making contact.

We are using black nitrile gloves.

The air filter has two tubes towards the front that need to be loosened. A flat screwdriver loosens the hose clamp on the air intake tube. The other hose is just pulled off but make sure the rubber gasket stays in place.

The electrical wires for the MAF sensor stay connected so you can’t totally remove the air box cover. Disconnect the wire on top of the box to get extra slack. 4th photo from the bottom. Be careful not to stretch

EPC electronic power control

This light came on. After replacing the engine speed sensor it went off. Our car drove terrible with this bad sensor. It stalled, started hard and shook to make early idle power. Finally it would not start. It was intermittent for about a month until it completely died.

Google Gardens

Google just decided to re-plant the orchards its offices replaced.

IMG_2751

The corporate yards which now cost the company to maintain its landscaping are going to be transformed into orchards and gardens. The plan is to partner with Garden of Ikeda in order to make this possible.

The corporate yard transformed into a garden should boost employeee moral and lower healthcare costs since the employees will know have access to great food. The excess food is going to be donated to the near by displaced homeless people who now can’t afford rent.
