Code 1-4-1

[cameron]

My mate has a 95 Auto and the code 1-4-1 is coming up on the diagnostic module behind the drivers headlight

1-4-1 oil temp sensor circuit short to earth

Where do i look or how do i solve this problem ?

Cheers guys

You sure that's the translation for that code?, I thought 1-4-1 was more to do with emmissions?, that's how I remember it anyway.

Not too sure tbh Craig, only going off this list ...........

1-1-1 no fault
1-1-2 solenoid s1 circuit short to 12 volts
1-1-3 ECU fault
1-1-4 break in drive mode selector circuit
1-2-1 Solenoid s1 circuit short to earth
1-2-2 break in solenoid s1 circuit
1-2-3 solenoid STH circuit short to earth
1-2-4 driving mode selector circuit short to earth
1-3-1 solenoid STH circuit break or short circuit to earth
1-3-2 fault in ECU
1-3-4 incorrect ignition module load signal
1-4-1 oil temp sensor circuit short to earth
1-4-2 break in oil temp sensor circuit
1-4-3 kickdown switch circuit short to earth
2-1-1 fault in ECU
2-1-2 solenoid S2 circuit short to 12 volts
2-1-3 throttle position signal too high
2-2-1 solenoid S2 circuit short to earth
2-2-2 break in solenoid s2 circuit
2-2-3 throttle position signal too low
2-3-1 irregular throttle position signal
2-3-2 no vehicle speed sensor signal
2-3-3 incorrect speedometer signal
2-3-5 oil temp too high
2-4-5 torque limiting circuit brake or short circuit to earth
3-1-1 No transmission RPM sensor signal
3-1-2 transmission RPM sensor signal faulty
3-1-3 gear position sensor (PNP) -incorrect signal
3-2-2 incorrect gear ratio for given roadspeed
3-2-3 lock up slippage or not engaging
3-3-1 solenoid SL circuit short to 12 volts
3-3-2 solenoid S2 circuit -brake in circuit
3-3-3 solenoid S2 circuit short to earth

To reset the dash light, clear all the codes until code 1-1-1 is displayed then hold the button for
6-7 seconds, release then as soon as the light illuminates again hold the button down for another
6-7 seconds, swith the ignition off and then back on this should clear all the lights and reset the codes.

it could mean that the live feed is touching some where or has a break in it thats causing the fault

[Tomcat]

I'll double check for you, has his lambda light come on?.

[cameron]

Yeah Lambda light on

[Tomcat]

Are you sure you've put the fly lead in the right hole?. socket 2 on unit A should be the fuel system. I've just checked the Hanyes book of lies and there's no 1-4-1 listed for the fuel system, there is one for the heater system though.

[cameron]

Ah ok, im seeing him tomorrow, i'll give it another go

[Tomcat]

If you get stuck mate give me a ring, you still got my number?.

[cameron]

No mate i changed my phone and lost all my bloody numbers

While i remember, Pete ive lost your number as well
