code o0197 and 4460 HELP


Recommended Posts

hi all i need ur kind help with the following

1-

p0197 Oil temperature

i changed the sensor and still its not working i cant know the oil level coz am getting engine is not worm massage , durametric is giving me this code again and again , i understand it could be the harness or the DME(hopefully not) , how can i check the wiring ? i want to check if the wiring is ok (grounding maybe ?)

2-

4460 Pressure sensor

when i reach the speed of 50kilo/m i get PSM/ABS

how can i troubleshoot the system ?below 50km the ABS seems to work fine

thanks in advance

thanks sir for the replay ,,,

but ,i dont have the special tool nor the knowledge to follow these instructions ,,, for now i am really worried about knowing my oil level , so i need to fix the oil temp sensor ,,,

i took alook and the switch it seems fine to me ,,, is there any easy way to solve this problem ?

regards

maybe there is way to know which pin refers to oil temp sensor from the DME side so i can check for continuity ?

Been out all day, but had a look at the wiring diagram. Nearly all the signals go to the instrument cluster first not the DME.

Here are the pin numbers required at the instrument cluster:

B18 ground oil level colour Br/Or

B2 Oil level Colour Gn/Bu

B5 Oil Pressure Colour Gn/Rd

A13 Oil pressure switch Colour Gn/Wh

I will look to see if I can find some more .

Frank

Right also found the Motor Oil Temperature goes to the DME pin C5 Colour Gn/Rd.

Apart form oil temp it would appear the DME doe not have anything else to do with the oil pressure or level

:)

My problem is with the oil temp ,,, i am getting the code and also i cant read my oil level because the cluster is giving me a msg that the engine is not wormed up ,,,

i changed the oil sensor and still the same problem ,i am thinking of removing the sensor switch to see if i get a different code other than p0197(LOW Voltg) and that will indicate that the harness is fine ??? what do u think ???

Why don't you try doing a continuity test from the oil temp sensor to pin C5 on the DME. Remove the plug so its not connected to the dme, then you cant do any harm. See if there is a break in between C5 and the temp sensor plug.

Or run the engine to normal temp, then measure the resistance of the temp sensor.

60 °C 2.8 - 3.5 kΩ

90°C 1.0 - 1.3 kΩ

120°C 0.4 - 0.6 kΩ

I would think you should be in the range of 90°C 1.0 - 1.3 kΩ.
