Instead of trying to bypass it, you need to diagnose and fix the problem that triggered limp mode. Here's what you should do:
1. Check the Check Engine Light (CEL): If the CEL is on, it's crucial to get the diagnostic trouble codes (DTCs) read. You can do this in a few ways:
* OBD-II Scanner: A relatively inexpensive OBD-II scanner from an auto parts store can read the codes.
* Auto Parts Store: Most auto parts stores will read the codes for free.
* Mechanic: A qualified mechanic can diagnose the problem much more effectively.
2. Address the Underlying Issue: Once you know the DTCs, you can research the likely cause. Common causes of limp mode include:
* Low transmission fluid: Check your transmission fluid level and condition. If it's low or dirty, it needs to be addressed.
* Faulty sensors: Various sensors (e.g., oxygen sensor, mass airflow sensor, crankshaft position sensor) can trigger limp mode. These often require replacement.
* Electrical problems: Wiring issues, shorted circuits, or faulty connectors can also cause limp mode.
* Transmission problems: More serious issues like worn clutches or internal transmission problems may require a costly repair or rebuild.
3. Repair the Problem: Once the underlying problem is identified, it needs to be fixed. Attempting a repair yourself might be possible if you're mechanically inclined and have the proper tools and knowledge, but it's often best to leave this to a qualified mechanic, especially for transmission-related issues.
Trying to bypass limp mode without addressing the root cause is incredibly dangerous and could result in:
* Severe engine damage: Continuing to drive with a faulty engine component could lead to a complete engine failure.
* Transmission failure: Ignoring transmission problems will likely worsen the damage and lead to costly repairs or replacement.
* Safety hazards: A malfunctioning engine or transmission can cause loss of control, leading to accidents.
In short, don't try to bypass limp mode. Fix the problem that caused it. Getting the codes read is the first and most important step.
