Codes P2135, P2138 and P0641?

Here are the code meanings:

P2135: Throttle/Pedal Position Sensor/Switch 'A'/'B' Voltage Correlation

P2138: Throttle/Pedal Position Sensor/Switch 'D'/'E' Voltage Correlation

P0641: Sensor Reference Voltage 'A' Circuit/Open

The P0641 is the problem you have an open circuit and a problem with the five-volt reference which can be the PCM itself. So, let's check the five volts at the TPS inside the throttle body and the throttle position sensor or APP.

Also, we should check the hand full of fuses that run the system which I have included as well in the images below.

Here are the wiring diagrams and I have marked the wires you should check with the key on. If you have no 5 volts on either of these wires and the fuses are all good, I would swap out the PCM with a preprogrammed unit.

POWERTRAIN CONTROL MODULE (PCM) REPLACEMENT

Service of the powertrain control module (PCM) should normally consist of either replacement of the PCM or electrically erasable programmable read only memory (EEPROM) programming. If the diagnostic procedures call for the PCM to be replaced, the PCM should be inspected first to see if the correct part is being used. If the correct part is being used, remove the faulty PCM and install the new service PCM.

IMPORTANT:
- To prevent internal PCM damage, the ignition must be OFF when disconnecting or reconnecting power to the PCM. For example, when working with a battery cable, PCM pigtail, PCM fuse, or jumper cables.
- Remove any debris from the PCM connector surfaces before servicing the PCM. Inspect the PCM module connector gaskets when diagnosing or replacing the PCM. Ensure that the gaskets are installed correctly. The gaskets prevent contaminant intrusion into the PCM.

Removal Procedure
1. Using a scan tool, retrieve the percentage of remaining engine oil. Record the remaining engine oil life.

IMPORTANT: It is necessary to record the remaining engine oil life. If the replacement module is not programed with the remaining engine oil life, the engine oil life will default to 100 percent. If the replacement module is not programmed with the remaining engine oil life, the engine oil will need to be changed at 5000 km (3,000 mi) from the last engine oil change.

Installation Procedure

1. Install the PCM mounting studs (5) to the intake manifold, if removed.

NOTE: Refer to Fastener Notice in Service Precautions.

Tighten the studs to 6 N.m (53 lb in).

2. Install the PCM (1) onto the studs (5).
3. Install the PCM retaining bolts (3).

Tighten the bolts to 8 N.m (71 lb in).

4. Install the PCM retaining nuts (6).

Tighten the nuts to 8 N.m (71 lb in).

5. Install the PCM harness connectors (2) to the PCM body.
6. Tighten the PCM harness connector retaining bolts (4).

Tighten the bolts to 8 N.m (71 lb in).

7. If a new PCM is being installed, the PCM must be programmed. See: Vehicle > Programming and Relearning
