Code P1701 Buick Description
The P1701 Buick code refers to a Transmission MIL Request Circuit error. This indicates that there is a problem with the communication between the transmission control module (TCM) and the engine control module (ECM). The TCM is responsible for controlling the transmission's shifting patterns, while the ECM manages the engine's performance. When there is a breakdown in communication between these two vital components, it can lead to a variety of issues with the vehicle's transmission and overall performance.
Common Causes of P1701 Buick
- Faulty transmission control module (TCM)
- Loose or corroded wiring connections between TCM and ECM
- Electrical issues within the TCM or ECM
- Failed transmission speed sensors
- Software or programming issues within the TCM or ECM
Symptoms of P1701 Buick
- Malfunction indicator lamp (MIL) illuminates on the dashboard
- Transmission slipping or jerking during gear shifts
- Delayed engagement when shifting into gear
- Transmission overheating
- Reduced fuel efficiency
How to Fix P1701 Buick
- Begin by performing a thorough diagnostic scan to confirm the P1701 code and identify any additional transmission-related issues.
- Inspect and test the wiring connections between the TCM and ECM to ensure they are secure and free of corrosion.
- Test the transmission speed sensors to determine if any are faulty and replace as necessary.
- Check for any software or programming updates for the TCM and ECM and perform updates if available.
- If the TCM is determined to be faulty, it may need to be replaced and reprogrammed to ensure proper communication with the ECM.

Frequently Asked Questions about P1701 Buick Code
1. What does the OBDII code P1701 mean on a Buick?
P1701 indicates a problem with the Transmission MIL (Malfunction Indicator Lamp) Request Circuit, which is responsible for signaling a transmission fault to the vehicle’s engine control module (ECM).
2. What are common symptoms of the P1701 code in a Buick?
Symptoms may include the check engine light or transmission warning light illuminating, erratic shifting, transmission performance issues, or the vehicle entering "limp mode."
3. What causes the P1701 code to appear on a Buick?
Common causes include a faulty transmission control module (TCM), wiring or connector issues in the transmission MIL circuit, or a malfunctioning ECM.
4. Can I continue driving my Buick with a P1701 code?
You may be able to drive the vehicle, but continuing to do so can lead to further transmission damage or reduced performance. It's best to address the issue promptly.
5. How do I diagnose the P1701 code on my Buick?
Diagnosis involves using an OBDII scanner to confirm the code, visually inspecting the wiring and connectors in the MIL circuit, and testing the TCM and ECM for proper operation.
6. What repairs can fix a P1701 code on a Buick?
Repairs may include fixing or replacing damaged wiring, repairing corroded or loose connectors, reprogramming or replacing the TCM, or addressing ECM-related issues.
7. How much does it cost to fix a P1701 code on a Buick?
Repair costs vary based on the cause, but fixing wiring or connectors typically costs less than replacing the TCM or ECM, which could range from $300 to $1,200 or more.
8. Can a weak battery cause the P1701 code on a Buick?
A weak or failing battery can sometimes cause electrical issues, including this code. Ensure your battery and charging system are in good condition.
9. Does the P1701 code mean my transmission is failing?
Not necessarily. The code indicates an issue with the communication circuit, not necessarily the transmission itself, though transmission issues could trigger this fault.
10. Can a software update resolve the P1701 code on a Buick?
In some cases, a software update for the ECM or TCM may resolve the issue, especially if the code is related to a known bug in the vehicle’s software.
