m.7.4.4 ecu
2001 saxo vtr lambda faults
po134 oxygen sensor
p0135 upstream heating command
p1327 ignition integrated phase detection

replaced sensor
swapped ecu, checked wirng for continuty between sensor and ecu, all ok

downstream goes active upstream stuck on .44v

P0134 (No activity) and P0135 are probably linked.
The heater for the sensor doesn't work.
That may be a fuse, wiring, the sensor or even the ecu.

P1327 is a problem with the coil. The coil provides the camshaft signal. Usually this means a new coil.

Back you up on that one.

If the costomer is Polish - tell him he needs to try some new "Candles"
If the costomer is Inglish, tell him he needs to try new "SPARK PLUGS"
