Ok so I got this car with dtc # p0339 and p1298. I checked for batt. voltage at yel/blk wire and got 10.37 volts, blu wire I get 5volts and at yel/blk jumped to brn/yel wire I get 9.53 volts. Battery voltage is at 12.43 so there is a drop on volts to the sensor question is is this ok ? I still went ahead and replaced the sensor with an aftermarket part and I still get the code p0339. At first start it turns on and shuts down code returns, if I step on the gas it stays on. Once it starts it runs fine at idle have not test driven yet because code comes on.
Second code p1298 ELD circuit high voltage, I followed the flow chart and found that the ELD is bad because the voltage does not drop as specified on step 15. Now that leads me to the next question can this effect the crank sensor.
P.S does anyone have a good cam/ckp wave form.
Thank you for your help.
