Torque Request Signal Denied
The vehicle's control module is not receiving the correct torque request signal.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The module in charge of controlling engine power is getting told that it can't use the requested power, which can slow down your acceleration.
What the computer is actually seeing
The control module expects a specific torque signal to manage engine power delivery. If it receives a conflicting or invalid signal, it sets the C1049 code.
What a healthy reading looks like
The torque signal should typically be within a range of 0-100 Nm (Newton meters) for proper function.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the wiring and connectors related to the torque sensor for damage or corrosion. If found, repair or replace as necessary. Decision Point: Did you find any issues? If yes, fix them and retest. If no, move to step 2.
- 22. Check the torque request sensor operation using a scan tool. Compare live data with expected values (should be 0-100 Nm). Decision Point: Does the data match the expected range? If yes, move to step 3. If no, replace the torque request sensor and retest.
- 33. Inspect the control module for fault codes or issues. Ensure it's receiving and processing signals correctly. Decision Point: Are other codes present? If yes, address all related codes before retesting. If no, replace the control module if necessary.
Common causes
- Faulty or corroded wiring to the torque sensor
- Failed torque request sensor
- Electrical interference from surrounding components

Frequently asked questions
Is it safe to drive with this code?
Moderate severity indicates you should fix it soon, as it can impact drivability.
Will this code come back after clearing it?
If the underlying issue isn’t fixed, yes, the code will likely return.
Why does this code sometimes pair with C1048?
C1048 relates to the torque request being invalid, while C1049 indicates it's being denied, so they often occur together.
