The code was P0641?

The P0641 diagnostic trouble code indicates an issue with the 5-Volt Reference 1 Circuit. Can I ask what the connector goes to? That way I can get the wiring diagrams for repairs.

Please give me the code numbers so I can help you. I can tell you that the limp mode can be caused by a bad throttle body or if it needs to be cleaned which you can try first.

Here are two guides to help us while you get me the code numbers:

and

Here is how to service the throttle body on your car. Check out the images (below). Please let us know what happens.

Sounds good, I can't read the codes. Can you please list them in your post?

So the first code will cause the problem and the third code, let's try replacing the accelerator pedal sensor and then clear the codes.

P2122 - Throttle/Pedal Position Sensor/Switch 'D' Circuit Low Input
P0452 - Evaporative Emission System Pressure Sensor/Switch Low Input
P0641 - Sensor Reference Voltage 'A' Circuit/Open

Here is how to replace the part in question. Check out the images (below). Please let us know what happens.

So now there is no P2122 code?

Please start a new thread with the new codes.

What wiring diagrams do you need?

Here is the camshaft sensor wiring.

Sure, can I ask what the connector plugs into? Here is the x100 connector info. Check out the images (below). Please let us know what happens.
