182 in limp no coolent Temperture showing

[thenorth]

So yesterday started up my 182 everything seamed fine, i set off but i quickly realised i was in limp mode so i pulled over switched it off read the code with code reader.

it read p0135 which is upsteam lambda? i am getting 39mpg so lambda seams fine?

i also noticed the temperture guage wasnt raising at all. So after reading the code i switched it back on and everything was fine.

it seams like the temp sensor cant read very low coolent tempratures but as soon as the engine is a tiny bit warm works fine?

any advise

Have the thermostat operation checked and maybe fit a new temp sensor?

ok so a little update i have run the car for 5 mins with the RSTUNER live info running.

anyone got any ideas? seams like front lambda is stuck on minimum ?

A good basic check on a lambda sensor is to test the resistance of the heater element. A broken element would give an OBD fault code, show signs of poor running at idle, but may be okay at higher speeds, ie. when the exhaust gases have an opportunity to heat up the sensor to its proper working temperature.Make sure the exhaust is cool. Disconnect the sensor's wiring harness and set your multimeter to read 'Ohms'. If the meter isn't auto-ranging, select the 200 Ohm scale. Connect the meter to the two heater wires. The table on this page will tell you common wiring colours, but it is often the two white wires. If, like this Ecotec sensor, the connector pins are difficult to get to, insert two pieces of thin wire into the connector holes where the white (heater) wires are, or use an insulation piercing test probe.​
