2001 trajet. automatic box output speed sensor

Go to autozone or similar and have it scanned for free

maybe just a bit of un burnt fuel, if it has done it only once , common at high speed to leave unburnt fuel in cylinder when taking pressure of the accelerator

on the gearbox will have a connector with 2 wire coming from it and the end of switch will have a nut shape so can be undone

It appears that another Hyundai owner had the same problem and sorted it out himself. U0D00 seems to be the Mass Airflow meter (sensor). Replace it and see how it performs. Good luck.

Is under crankshaft pulley.

Hyundia trajet as just started to blow grey smoke can you help

drive the car in 2nd speed gear at1000 - 1200rpm to form number 8 shape like zig zag manner,if you find taka taka taka noise,the drive shafts are weared out.

it is inside the timing cover in most cases with hyundai the timing belt will have to be removed so the crank gear can come off the sensor is usually behind the gear especially if it is a 6cyl if it is a 4 cyl then the wire goes behind the timing belt make sure the timing marks are lined up so when you reassemble it is lined up

Priced new output speed sensor €190, went to breakers yard, found similar sensor on mitsubsihi carisma, purchased €20, fitted same no problems since. Touch wood!
