Peugeot Transmission oil pressure switch replacement
When Does My Peugeot Transmission Oil Pressure Switch Need to Be Replaced?
A transmission oil pressure switch is responsible for monitoring your Peugeot's transmissions oil pressure.
This information is then sent from the transmission to the ECU which it uses to make sure that gear changes happen at the appropriate time.
There could be a number of ways that you can tell if your transmission oil pressure switch has an issue
1. Engine light on
Generally, your first inclination that something is wrong is the engine light coming on, This could come on for a variety of reasons so it’s best to get it in to get checked out ASAP
2. Peugeot has difficulty shifting
If the switch is registering a different pressure than what is in the transmission then it can cause the transmission to shift too early or too late causing the shift to feel harsher than usual.
3. Engine RPM is higher than it should be
Similar to the above reason, a mismatch in the oil pressure switch compared to what's in the transmission can cause your Peugeot to rev a lot higher before it shifts.
4. Peugeot enters "limp" mode
If your transmission oil switch registers your transmission oil pressure is too high or low, it may send your vehicle into limp mode. Limp mode is when you're still able to drive your vehicle, however, the transmission will stay in a single gear to prevent any further damage. This should allow you to get your car to a safe place, or even to the nearest workshop.
The transmission oil pressure switch is vital for the smooth and efficient operation of the vehicle. If you recognise any of the above warning signs or symptoms, get it checked out ASAP
Generally, it's a pretty simple repair because the oil pressure switch is easy to access. Parts prices can vary from model to model and can sometimes be difficult to source, which could cause delays in the repair.
Some things that to remember if you think you have a transmission oil pressure switch issue
- If you notice your Peugeot's transmission starting to shift erratically or harshly get it checked out ASAP
- If you leave it too long your vehicle may go into limp mode or may require a costly tow.
