Dodge installed VNT Turbochargers on cars in 89 and 90. The most well known of which is the 1989 Shelby CSX-VNT. The vanes were controlled by a dual port vacuum actuator. There was nothing electronic on the turbo itself, but there were vacuum solenoids (for boost control) on the lines going to the actuator. The VNT Turbo has movable vanes on the exhaust ...
Disclaimer: I've never done this practically. This answer is based on my somewhat limited exposure to turbomachinery theory in automotive applications. It's all about the flow Unlike fixed-geometry turbos, in which the vanes provide optimal efficiency for a single flow, vane angles are adjusted in variable-geometry turbos to enhance efficiency across a ...
I think you need to give more information about the application to attract answers. For example, define "dissipate": do you mean to scrub off enough thermal energy to bring temps to within 2 degrees of ambient? 20? 200? Is the goal to use this intermittently or for constant use? Big difference in BTU's there. And is your goal to bring the shaft to 0 rpm ...
On a modern car, there's no real work to be done after physically replacing the part. You can disconnect the negative battery for 10-15 mins to reset the computer and have it relearn its mappings, but that's not strictly necessary.
I think you misunderstand the purpose of the Mass Air Flow (MAF) sensor (and whoever wrote what you read doesn't understand, as well). The purpose of the MAF is to read the amount of incoming air. As the incoming air flows over the heated sensor, it cools the sensor which regulates the amount of electricity which can flow through it. It is in no way ...
Start the engine and turn on the head lights and rear screen heater then check the battery voltage, it should be 13-14 volts. If it is less than 13 volts, then your alternator is faulty. If the CEL came on while starting the engine it could be the low battery voltage that confused the ECU. It is possible that something is drawing power from the battery ...
I believe you already found the culprit. If you can 'jiggle' wires in the harness and cause any change in how the engine is running this is NOT normal. Unfortunately this is one issue that has to be diagnosed in-person as there are too many variables when it comes to wiring. Start by checking ground wiring first. This is easiest to do because you can ...
I'm not sure which engine the Z5 is, but this is the procedure for the 1997 Mazda Protege engines. The Protege's are called 323's elsewhere in the world for those years.
The vehicles engine map will be the differance. If you are using a throttle body spec for a differant set up then it is bound to be wrong. The TPS may also vary on model to model.
Are there any other electrical problems? When you restart the car the problem can still be there, but it resets. If there are other electrical problems, these could be the culprit simply affect the sensor.
