QuestionHi Kevin, this is a question I have asked Roland when you were on holiday and his answer. I have a follow up question, but I do not seem to be able to place it before he maxes out. I hope you do not mind if I ask you instead:
Original question:
Hi Roland, I have Plymouth Grand Voyager 3.3SE (1997). It recently had oil changed (10W-30) and oil filter and spark plugs replaced. After the change, when the car is driven for about 3-4 minutes, the oil pressure light and a chime come on. When the car is stationary and the engine running (even for more than an hour) it never happens. The oil level is OK, there are no leaks and the oil is still nice and clean. I have noticed that somehow the knock sensor broke off (I have already ordered a new one) – is there any possible connection? Also, where can I buy the oil pressure gauge for this vehicle?
Finally I also need to replace wheel speed sensors, since the ABS light is on and the code readout indicated the faulty sensors - will the light reset itself after replacement of the sensors, or do I just disconnect the battery for a while? Many thanks for your help. Kind regards, Boris.

Answer Hi Boris,
If you mean the oil pressure "sender" (that operates the warning light) that should be available at a dealer or a professional parts store. Is it possible that the oil that was used was 5W-30? If not, then try a new sender. It is located next to the oil filter. I don't believe the knock sensor has anything to do with the oil pressure sender, unless both were damaged simultaneously.
The abs fault codes will reset if they are no longer relevant, but only after driving 3500 miles. They can also be erased with the Chrysler Diagnostic Readout Box III or equivalent if you don't want to wait that long. Disconnecting the battery won't erase them.

Follow up question:
Here are few points for clarification: 1. I meant the oil pressure gauge (to be put in place of the oil pressure sender) the measure if there really is insufficient oil pressure – I did not find any place here in the UK to buy one. A related question – could I use a higher viscosity grade oil (say 20W/40) to see if that would solve the problem? The second problem is that 3500 mile resetting distance for the computer code related to the ABS light on is a bad news for me. The main Chrysler dealers here in the UK charges $200.00 just for getting the readout and another $200.00 to get the computer reset, unless you let them to fix the problem – in this case they quoted me $800.00 to replace both front wheel speed sensors on the top of charge of the readout. I can get the sensors for about $140.00 including delivery to the UK, so it seemed to me a bit over the top. So the question is: if I replace the computer (about $170) after replacing the faulty wheel sensors – will that fix the problem? (I hope the memory is part of the computer and not a separate part).
Many thanks for your help
Answerdifferent oil wright will not fix a low oil pressure issue either pump or screen or internal engine issue.
the abs lights will go away if U replace the sensors and if that is the issue with in the first few miles. and if u put a new computer on U will haft to have it programed by the tire size.
