On the GPIO, the connections are: You need a minimum 4. This resistor dissipates up to 4 Watts of power at low line pressures maximum PWM percentages. As a result, the resistor can get hot, so mount it on a heat sink ideally a metal block in an area with plenty of air circulation. In conjunction with that resistor, you will need a 1N diode placed between pin C and D on the 4L60E connector the closer to the transmission connector the better. These two additional components cut the flyback spikes from the solenoid to manageable levels preventing damage to various GPIO board components and potentially cleaning up external signals such as the VSS.
Notes on the Troubleshooting and Repair of Video Cassette Recorders
Media reaction to the ZR-1 was initially fantastic. Within days of its unveiling in Geneva, the ZR-1 owned the cover of virtually every magazine in the world. The first significant improvement to the Corvette in nearly half a decade involved the introduction of an entirely new manual transmission for the model year.
The all-new six speed manual transmission was introduced to the Corvette in and was designed as a joint effort between Chevrolet and Zandfabrik Friedrichshafen. The arrival of the new six speed transmission would be met with unquestioning approval, although its introduction would carry with it a certain amount of controversy as well. For the series, Chevrolet built sixty cars, thirty of which would have their stock engines swapped with higher-output engines from the CPC Chevrolet-Pontiac-Canada group engine plant in Flint, Michigan.
Slotted design allows removing oxygen sensor with wiring harness attached. LS Downstream O2 Sensor Harness 24″ Extension Wideband LS3 LS1 LQ4 LSX, by ICT Billet. $ $ 19 99 Prime. FREE Shipping on eligible orders. Only 8 left in stock – order soon. Product Features GM .
Early production was a Gen3 engine in the “classic body style truck” Please let me know if PCM does not match the engine exactly. GM used different injector sizes, fuel rail types etc across engine’s and years. It’s important for best performance to know exactly what the engine is. Also, if you plan to swap intakes from another engine LS1 intake on a 5. Supplying an 8 digit injector number found on side of each injector will always help insure correct flow rate is programmed into the PCM.

This condition might also occur also with power-vented equipment in some conditions. Other reasons for flue gas spillage: Other reasons that a gas flame may be lost or a gas fired appliance shut off on safety may have nothing to do with bad flame or bad combustion air.
Jan 19, · The O2 or Oxygen sensor is in charge of measuring the content of the exhaust. Learn about the O2 sensor electrical connection and how it relates to the ECM and signal output.

They help determine, in real time, whether the air—fuel ratio of a combustion engine is rich or lean. Since oxygen sensors are located in the exhaust stream, they do not directly measure the air or the fuel entering the engine, but when information from oxygen sensors is coupled with information from other sources, it can be used to indirectly determine the air—fuel ratio.
Closed-loop feedback-controlled fuel injection varies the fuel injector output according to real-time sensor data rather than operating with a predetermined open-loop fuel map. In addition to enabling electronic fuel injection to work efficiently, this emissions control technique can reduce the amounts of both unburnt fuel and oxides of nitrogen entering the atmosphere.
Unburnt fuel is pollution in the form of air-borne hydrocarbons, while oxides of nitrogen NOx gases are a result of combustion chamber temperatures exceeding kelvins due to excess air in the fuel mixture and contribute to smog and acid rain.
When you thought it couldn’t get any better, Kawasaki releases the Ultra X and writes a new book in high performance watercraft. Hands down the Ultra X is the best handling, most powerful watercraft ever produced. Kawasaki has raised the standard of performance watercraft to a level previously only accessible to Pro Open class racers. Right out of the box, the Ultra X feels like a thorough bred race craft.

Next Is it possible that an upstream oxygen sensor has the same electrical connector as a downstream same car? I have a Mazda Protege, and have had a scan code of bank 1 sensor 2. Bought a new O2 sensor. Looked up the part online- it says downstream. I’ve found an 02 sensor on my car with same electrical hookup as the new part, but It looks like it’s before the catalytic converter. Is it possible that an upstream sensor would have same connection as downstream?
The part on box says it’s downstream and looks like right part.

Replacing the Oxygen Sensor on a Chevy Truck by Russell Wood A fuel-injected engine uses many different sensors to determine how to make your engine run properly. The and newer GM trucks use one or more oxygen sensors located along the exhaust. They’re not difficult to replace, but they can take some elbow grease and some basic safety equipment to do properly. Lift the Truck First, make sure the vehicle is turned off, has cooled down for a few hours and the emergency brake is set.
Using a jack, lift the front of the truck so that the front tires are off the ground. A good jack point is the front crossmember, or alternatively, the sides of the frame below the doors.
Apr 22, · How to replace the old oxygen sensor with a new one. And which is the best tool to use.
Each sensor has enough length of sensor wire to allow maximum replacement of worn harnesses. Has your vehicle failed a state emissions test? Your vehicle’s emissions control system is in need of repair, but before you waste As one of the leading suppliers of oxygen sensor technology since , Delphi planar technology is the result of their OE and aftermarket engineers partnering together to develop the most Designed utilizing the latest technology, this product by ACDelco features premium quality and will perform better than advertised.
Perfect for your vehicle and lifestyle, it is The Positive Crankcase Ventilation PCV system prevents the release of harmful emissions, helps keep engine oil clean and prevents excessive crankcase pressure, which can cause oil leaks.

Be sure to save the illustrations separately. The opinions expressed here are my experiences, and your experiences may vary. I don’t put myself forward as the world’s leading expert on Holleys, but I do have some helpful ideas. In some cases, I may not be able to answer specific questions, but I’ll do my best. I know very little about other brands of carburetors and have no information about them, only general operating principles.
I have NO experience with any type of supercharger or turbocharger, so please don’t ask me anything about your blower or turbo applications.
The smaller the amount of oxygen that is left in the exhaust, the richer the A/F ratio is, and the higher the oxygen sensor voltage is. The on-board computer or Powertrain Control Module (PCM) monitors the voltage from the oxygen sensor.
Originally Posted by smj smj Actually, the front oxygen sensor is very important and the main input for the ECM to determine the richness and leaness of the mixture. Well sure, I get that. What I’m saying is, that all other things being equal, a well tuned engine with an ECU that has recently updated Short Term and Long Term trim values and updated ‘tables’ is just as capable of running well ‘open-loop’ as it is ‘closed loop’, just won’t run nearly as efficient or clean in ‘open-loop’.
Now, if the sensor was partially out and giving crappy readings i. But if that front O2 sensor is completely dead i. If the ECU is compensating for something else i.
