Camshaft Position Sensor Location and Replacement?

Hi,

You are very welcome. I have a feeling that replacing the other sensor isn't going to remedy the problem. The code you have is specific to the sensor you already replaced.

Here is the actual flow chart for diagnostics related to this code. I feel bad attaching it. LOL I don't how comfortable you feel doing it, but thought it may be of interest to you. If you look at that last pic I attached, it shows a list of things that can cause this code.

It's likely that you now hate me for attaching this. LOL Regardless, let me know what you find.

Take care,
Joe

Good morning,

I attached a picture of the locations of the sensors. You have 4 sensors, 2 intakes, and 2 exhaust.

Why are you replacing the sensor? Was there a code? If there was, what is the code?

Roy

There isn't a traditional regulator on this vehicle. It is controlled by a two fuel pump control modules. The two fuel pump control modules modulate the voltage to the 2 fuel pumps (FP) required to achieve the correct fuel pressure. Voltage for the two fuel pumps is supplied by the power relay and fuel pump control module relay. See pic 1. On the fuel rail is a FRPT sensor which signals the control module of real time pressure so the module can adjust voltage to the pumps.

Let me know if this helps explain.

Joe

Okay, bank 1 is the passenger side of the engine. The sensor is the one that is closest to the exhaust manifold.

This code indicates a voltage issue with the wiring. I would verify there is 5 volts to the sensor and the return line to the ECM is not damaged or open.

Roy

At this point, I would simply start by testing fuel pump pressure at the fuel rail to see if it is within the manufacturer's specs. Here is a link that shows in general how it is done.

____________________________________

Here are the directions specific to your vehicle. You will need a fuel pressure gauge, but most parts stores will lend one to you with hopes of selling you a new part. lol

The attached pics will correlate with these directions.

Check
NOTE: This Fuel System Pressure Check is for the low pressure side of the system.

1. Release the fuel system pressure.
Refer to: Fuel System Pressure Release See: Fuel Pressure Release > Procedures > Fuel System Pressure Release (310-00A Fuel System - General Information - 2.7L EcoBoost (238kW/324PS), General Procedures).

2. Disconnect the battery ground cable.
Refer to: Battery Disconnect and Connect See: Battery > Procedures > Battery Disconnect and Connect (414-01 Battery, Mounting and Cables, General Procedures).

3. Remove nuts and the engine appearance cover.
Torque : 42 lb.in (4.8 Nm)

4. Remove the High Pressure Fuel Pump noise insulator.

pic 3

5. Disconnect the fuel supply line-to-high pressure pump quick release coupling.
Refer to: Quick Release Coupling See: Fuel Line Coupler > Procedures > Quick Release Coupling (310-00A Fuel System - General Information - 2.7L EcoBoost (238kW/324PS), General Procedures).

6. Install the Fuel Pressure Test Kit between the fuel supply line and the high pressure pump.
Use Special Service Tool: 310-D009 (D95L-7211-A) Fuel Pressure Test Kit.

pic 4

7. NOTE: The Fuel Pump (FP) control module electrical connector was previously disconnected to release the fuel system pressure and must be reconnected to test the fuel system pressure.

Reconnect the Fuel Pump (FP) control module electrical connector.

8. Reconnect the battery ground cable.
Refer to: Battery Disconnect and Connect See: Battery > Procedures > Battery Disconnect and Connect (414-01 Battery, Mounting and Cables, General Procedures).

9. NOTE: Carry out a Key ON Engine OFF (KOEO) visual inspection for fuel leaks prior to completing the fuel system pressure test.

Test the fuel system pressure to make sure it is within the specified range. For additional information, refer to Specifications.

10. After completion of the fuel system pressure test, disconnect the battery ground cable, open the drain valve on the Fuel Pressure Test Kit and release any residual fluid into an appropriate container.
Refer to: Battery Disconnect and Connect See: Battery > Procedures > Battery Disconnect and Connect (414-01 Battery, Mounting and Cables, General Procedures).

11. Remove the Fuel Pressure Test Kit by reversing the installation steps.

The last pic shows pressure specifications.

Let me know what you find.

Take care,
Joe

The ones that are closest to the exhaust manifolds.

Roy

LOL. Did you get it going again?

Joe

Okay, I posted the 369 possibilities as well.

Check the connectors to all 4 sensors.

Roy

It doesn't fit into the same kind of recess exactly like the cam sensor, which makes it way harder to line up the bolt. It truly takes patience and you have to hold your tongue just right to get that bolt lined up perfectly. I usually put my finger in the area to feel for it to determine the location and to sum up about how far it is before I try to put the sensor in.

I attached a picture below of the PCM's location. Part number (GD9Z12A650AANP), so you have the correct number. Interestingly, the directions to remove and replace refer to it as a PCM, but under the parts, it is referred to the ECM. They are the same thing. LOL

Let me know if this helps.
