[Warning Light] Stop light?

[Jensen]

anyone had a problem with the stop light coming on, temperature going right up and fan kicking in? Can't seem to find the cause? Changed the thermostat and a brown temperature sensor but it still happens anyone got any other ideas? Much appreciated

It's endemic! My personal suspicion is that something is upsetting the sensor feed voltages.

I'll get it checked out! Any idea what the voltages should be as normal?

[addo]

Yes, sensor reference voltage is 5.00V but if it dips or spikes you get a dishonest result from sensors.

spot on mate thankyou, I'll get it checked out and post back with results!

Have you any idea if there's more than one sensor aswell? It's the 2.0 Hdi
