Engine codes

[Robwilks6]

My 2001 mk6 transit developed 3 codes on a diagnostic check, P1664, P1564 and B2141.
It has run brilliantly for the last year and done 10K miles. The codes won’t clear.
Does anyone have any idea where the problem might lie please

what google AI says

seems to be getting a bit better of recent weeks, you can now put in all three fault codes and it will give a full report ... don't know how long it will take them to generate links to different businesses who fix fuel pumps ..in your results ..that's probably on the cards

accurate i don't know,( if it gets any better knobby will be redundant . ) as when refreshed sometimes gives a different perceptive on it .but does save a hell of a lot of waiting ....like its i think its been 45 mins now ..and you could have had some info

what it says with seasrch line "P1664, P1564, and B2141 in a Ford Transit"

The fault codes P1664, P1564, and B2141 in a Ford Transit, particularly a diesel model, often indicate issues related to the fuel pump, engine control module (ECU), and vehicle's network communications.
P1664: This code signifies a malfunction within the injection pump control module. It can point to a problem with the EDC (Electronic Diesel Control) pump itself, leading to intermittent or complete failure to start.
P1564: This code indicates that the engine is requesting reduced fueling or that the injection pump control module is in a reduced fueling mode. It can be triggered when the engine ECU detects a problem with the fuel pump's ability to provide sufficient fuel pressure, potentially due to a failed pump or a timing issue.
B2141: This code suggests a Network Module (NMV) configuration failure. It can be related to communication problems between the ECU and other modules, including the fuel pump ECU. This can manifest as a communication failure within the vehicle's CAN bus system.
Possible Causes and Solutions:
Failed Fuel Pump:
The Ford Transit EDC pump, especially in older models, is prone to failure, leading to these fault codes.
Timing Issues:
If the pump has been replaced, ensuring the timing is correctly set is crucial. A slack timing chain can also cause these issues.
Communication Problems:
B2141 suggests a problem with the vehicle's network, possibly within the CAN bus.
Fuel Level Issues:
The ECU may reduce fueling to prevent running the fuel tank dry, potentially triggering P1564.
Troubleshooting:
Check for Fault Codes: Use a diagnostic tool to identify the specific fault codes and their causes.
Inspect the Fuel Pump: Check for damage or signs of failure.
Verify Timing: Ensure the timing of the fuel pump is correct.
Inspect Wiring and Connections: Check for any loose or damaged connections related to the fuel pump and ECU.
Test the CAN Bus: If B2141 is present, investigate the vehicle's network communication.
Replace the Fuel Pump if Necessary: If the fuel pump is determined to be the cause, it may need to be replaced.
Note: The specific causes and solutions may vary depending on the age and model of the Transit. It's recommended to consult with a qualified mechanic or technician for proper diagnosis and repair.

Generative AI is experimental.

BTW the EDC is a module that sits on top of the high pressure pump.. and can be fixed separately... by a number of companies that specialise in this ..for usually under £75

CANBUS - not sure that is related to a 2001 transit

Do you have a 2.0 FWD or 2.4 RWD..??

As our metalworker0 mentions, the P1664 & P1564 point to a dead or dying EDC on the fuel pump.

B2141 points to faulty EGR or it's wiring is not happy..

It’s a 2.4 rear wheel drive duro torq , it starts first time every time and runs smoothly, it’s a 3500 kg motor home and returns about 32 to the gallon

Try clearing the fault codes and see what comes back.
