Camshaft Position Sensor issue

[maxim2014]

hi all

engine difficult to start engine cold or warm same thing

erratic idling at first star then after while normal idling

hesitation when accelerating
when accelerate hard its sounds like shocking no response at hard acceleration

poor engine response poor engine performance

trouble cods

P0341 Camshaft Position Sensor CircuitRange/Performance 004 No Signal/Communication

sensor convector unplugged

p0343 Camshaft Position Sensor high input

????????? help

a4 b6 2003 2.0 alt engine

maybe start with a new cam sensor.

Is it plugged in? It is right under your nose when you open the bonnet.

replaced the sensor same issue

Check for 5v engine running across the plugs pins 1 and 3, red/black and black.

i used testing device has 5v lamp and 12v lamp i did check the pins 1 & 3 output 5v lamp on

some one told me that maybe there is play movement in intake cam shaft adjuster makes camshaft ruing off timing

The fault looks to be electrical but it is the AWA engine which suffers from problems with the mechanical side of the VVT, the ALT is much more reliable. You need to check the signal of the G40 at the ECU.

thanks man for your replays


today got new code after long driving P1340 Crankshaft position sensor and camshaft position sensor not corresponded
002 Lower Limit Exceeded


and new symptom


during driving at steady speed the car like cut off not staling but suddenly cut off it wont accelerate any more till i release my foot on the accelerator paddle and push accelerate again

The new fault code suggests that your valve timing is incorrect BUT thinking about it, the VVT unit could be having an influence here. The longitudinal installation engines with the aluminium sumps are very prone to sludge formation which can block the oil pick up and reduce oil pressure. As the VVT unit is operated by oil pressure the ECU would pick up a miss match between the G28 and G40 sensors but it won't pick up low oil pressure. I have had a lot of 1.8T engines suffer VVT unit problems due to oil pressure, the non turbo ALT is not as prone but thinking about where the car is, the possible poor quality of fuel and oil and it maybe that you need to remove the sump and check the oil pump pick-up strainer for obstructions or sludge in the sump.

This is a bad example of a 1.8T with a blocked pickup but this is without balancer shafts that the ALT engine uses.

thank you
i will check the oil pickup be back soon
