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 ???

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 .

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

:)

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

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

125 Oil temperature sensor - below limit

Diagnosis conditions

• Idle speed

• Time elapsed after engine start-up greater than 5 minutes

Possible fault cause

♦ Temperature sensor faulty

♦ Wiring harness

♦ DME control module faulty

Affected terminals

Terminal III/5 and III/17

Resistance values

60 °C 2.8 - 3.5 kΩ

90°C 1.0 - 1.3 kΩ

120°C 0.4 - 0.6 kΩ

0

Printed in Germany, 2000

Diagnosis/troubleshooting

Work instruction Display OK If not OK

1 Check temperature sensor

♦ Connect special tool 9637 to

wiring harness (DME control

module plug)

♦ Measure resistance between Pin

III/17 and Pin III/5

2.8 - 3.5 kΩ

(at 60 °C)

⇒ Step 2

Replace temperature

sensor

→ End

2 Check wiring from DME

control module to temperature

sensor for continuity

♦ Connect special tool 9637 to

wiring harness (DME control

module plug)

♦ Remove plug connection of temperature

sensor

♦ Measure resistance between

special tool 9637 Pin III/17 and

temperature sensor plug Pin 2

♦ Measure resistance between

special tool 9637 Pin III/5 and

temperature sensor plug Pin 1

0 - 5 Ω

⇒ Step 3

Repair wiring harness

→ End

3 Check wiring from DME

control module to temperature

sensor for short to

ground

♦ Connect special tool 9637 to

wiring harness (DME control

module plug)

♦ Remove plug connection of temperature

sensor

♦ Measure resistance between Pin

III/5 and ground

∞ Ω

⇒ Step 4

Repair wiring harness

→ End

4 Replace DME control module ⇒ Step 5

5 Perform adaptation ♦ Switch on the ignition

♦ Wait one minute

♦ Do not press the accelerator

♦ Switch off the ignition for at

least 10 seconds

♦ Read out the fault memory

→ End

2. 45-30 Fault code 4460

Pressure sensor

Diagnostic conditions

• Pressure sensor actual value is evaluated and displays an

implausible value

Possible cause of fault

♦ Short circuit to ground/voltage or open circuit in circuit to control

module terminals 25, 26 and 42

♦ Plug connection on stop light switch faulty

♦ Adjustment of the stop light switch not OK

♦ Wiring/ plug connection faulty

♦ Pressure sensor faulty (replace hydraulic unit)

Affected terminals

Terminals 25, 26 and 42

Diagnosis/troubleshooting

Work instruction Display OK If not OK

1 Visual inspection ♦ Check the pressure sensor plug

for damage and corrosion

⇒ Step 2 Repair pressure sensor

plug

2 Check supply voltage of

the pressure sensor for

short circuit to ground/

open circuit

♦ Switch off ignition

♦ Pull off pressure sensor plug

♦ Switch on ignition

♦ Measure voltage between pin 3

of pressure sensor plug and

ground

approx. 5 V

⇒ Step 3

♦ Display 0 V:

Short circuit to

ground/open circuit

in circuit between

PSM control module

plug pin 42 and

pressure sensor

plug pin 3

♦ Display > 11 V

Short circuit to voltage

between PSM

control module plug

pin 42 and pin 3 of

the booster pump

pressure sensor

plug, or PSM contol

module faulty

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

Hi all

only the driver side of the spoiler goes up and the other side is not moving at all ,,, any ideas ?

thanks and regards
