What sensors control fuel injectors?
The injector control pressure sensor is an engine management component that is commonly found on diesel engines. As its name implies, it is an electronic sensor that monitors the fuel pressure going to the injectors.
What happens if your injector pressure sensor is bad?
A faulty sensor can throw off the fuel mixture and cause the engine to experience misfires, a loss in power and acceleration, a loss in fuel economy, and in some cases even stalling. Similar symptoms can also be produced by other issues, so a proper diagnosis is recommended to be sure of the issue.
Can a check engine light set off an injector control sensor?
An illuminated Check Engine Light can also be set off by a wide variety of other issues, so having the computer scanned for trouble codes is highly recommended. Injector control pressure sensors are more commonly found on diesel engines, however they can also be found on vehicles equipped with gasoline engines.
Can a bad injector cause an engine to start?
If the control pressure sensor has any issues, the computer signal to the injectors can be thrown off, which may lead to issues when starting the engine. The engine may require more cranks than normal, or several turns of the key before it starts.
How to ensure fuel injectors are receiving the correct range?
Step 1: Turn the car on. Turn the key to the second (ON) position for this test. You want battery power flowing, but don’t want the engine running. Step 2: Set up DVOM to measure DC voltage. Use the lowest range possible if the meter doesn’t auto range.
How to troubleshoot the Jaguar XJ-S electronic fuel injection?
If you wish to understand or troubleshoot the Jaguar XJ-S electronic fuel injection system, it is highly recommended that you obtain a copy of “Understanding Electronic Fuel Injection, Ignition and Engine Management ” by Roger Bywater and available from AJ6 Engineering.
What kind of fuel injection did the XJ-S use?
FUEL INJECTION SYSTEM TYPES: The 1976-80 XJ-S used a type of Lucas fuel injection system based on a Bosch D-Jetronic design. From 1980 on, the cars used a system referred to as a Digital P, also similar to Bosch.
What should I do if my fuel injector is not working?
Hopefully, these tests have allowed you to find the issue with your fuel injectors; but, as mentioned before, it may not be an electrical problem that is causing the injector to malfunction. The next step if the injector resistance is normal would be to remove the injector and test the spray pattern it produces on an injector tester.
