Hi All,

Finally got quotes for a few things to get my vehicle going.
I am wondering what will cause a code 137 and 144.

I had an overheating twice and have to change HBV.
I am ordering parts and wondering if i will also have to order ECU.

i am ordering the ff.

1. HBV
2. Crank Sensor
3. Breather seals, gaskets ect.

Anything else with the codes that i mentioned.
Thanks

Fault codes for the V6 are here

137 is ECU High temperature
144 is Immobilisor

The 144 will stop the engine firing, you should also see the EML light flashing while you try and start. Sometimes caused by the chip in the key moving.

The ECU high temp I'm not sure of, If you can get it started, try running with the bonnet open and the cover off the ECU - small triangular box by the battery

Thanks actually the key fob circuit was stolen so the key is static without an electronic circuit.

is there something i can do to disable the immobiliser to make car start.

All the same i still want to change the crank sensor.

[DaviesEB]

Can you advice on this. In Africa the thermostat on most vehicles are removed. Where can i find the thermostat. Is it in the HBV.

Our temperatures are high From 30 degrees plus.

If the immobiliser is not even present then I think you will have problems getting it running. The ECU needs to handshake with the immobiliser to ensure the transponder has been detected before it will allow the engine to start. This is firmware inside the ECU so very difficult to bypass without hacking.

Then again, if you have had this car running, you must have at least the transponder (NOTE: this is separate from the fob transmitter. It's a little chip perhaps 5mm x 10mm that fits into the key).

Thermostat is in the VEE of the engine, at the front. You'll need to remove the plenum and intake manifold before you can see it.

Highly appreciate.
But with this 144 code i do not understand. That is the vehicle has been starting and running. What i do not want to do is to bring in parts and realise i left some parts behind.

What do i do with the 144 or do i first change the crank sensor and see what happens next.

If the engine starts.....ignore it......its probably an old code.

And if those are the only two codes you have, I dont understand why you are changing the crank sensor?

Changing the hbv is unlikely to cure an overheating problem...its more likely to be a blocked radiator or waterways around the engine.....i would try giving the coolant system a good flushing and refill, but remember to add 50/50 mix of antifreeze, sounds mad in a hot country but its acts as a lubricant as well

The overheating issue is related to the ECU electronics getting hot, NOT the engine!

I believe there is a cooling fan for the ECU enclosure in some climates. Maybe it's worth checking this is working OK?

Then again, that could also be an old code. The codes could really do with being cleared so we can see what remains current.

It's not impossible that an external problem is loading the ECU and causing it to overheat but I would expect some more trouble codes in that case.

How do i clear the codes? Do you want me to put the crank sensor back and try to start again?

it has been a month now.

Thanks
