Code po201. Lincoln 2007 mkz can anyone find pictures of the location of injectors or numbered diagram


this code refers to injector #1 which is at the front of the engine(passenger side) on the side of the engine that faces the firewall. the most common problem is the injectors go bad or plug up. replace the injector for cylinder 1.

Had car scanned and got codes PO301-PO201-PO740 where should I start?


http://www.edgeproducts.com/product_images/customer_support_article-pdf-39.pdf helps you identify the source of the codes to narrow it down. Just remember, with three codes, you need to solve the code problem that can impact the others as there is usually a dependency on other subsystems working for the automobile to function correctly.

What does code p0203 mean for bmw 318i


Nr 3 injector faulty or open circuit to nr 3 injector. You could swap injector to another cylinder, clear the code & see if the code changes to another cylinder (PO201 nr 1, PO202 nr2 etc) then you know the injector is faulty or you could just replace & clear & see how you go. Most likly cause is the injector.

Autozone reading PO113, PO201, PO204, PO300, PO342, P1627


You may be biting off more then you want to chew.
P0113 is intake air temperature circuit high input.
P0201 is injector circuit malfunction cyl.#1.
P0204 is injector circuit malfunction cyl.#4.
P0300 is random - multiple misfire detected.
There isn't just one reason why these codes came up. A scan-tool is needed to confirm live data and to run some tests to see if these codes are true. some codes come up because something else has malfunctioned.
The intake temp sensor sould be inside the MAF sensor.
You may have more questions, please ask away.
