Code P061b96

Some videos talk about gas pressure and some talk about camshaft.
what is it exactly and how to tackle the issue

Google search is all over the place for this error.
Fix the P034062 error first and recheck. Change the intake cam position sensor. No need to get the MB sensor. The Bosch part number is on the OE one and much less expensive. BTW — P034062 is also associated with the camshaft adjuster failures but the description is different.
Unusual that there aren’t 1 or 2 underlying codes with the P061b96. The description sounds like an ECU internal failure, but other bad inputs may trigger this. Some P061b codes are triggered by sensors on the transmission conductor plate. Not certain about this exact one. Maybe look at live data from the transmission and look for a missing input from one of the sensors. It’s a quick check that I think your scanner can do.

A while back I switched the exhaust sensor with the intake one to check whether the sensor is bad, however the code p0340 retuned.
I’m hoping still the sensor and not the adjuster.
Would you check the images below to see transmission data

It looks like all 4 inputs are there. N1, N2, N3 all give readings. N4 is 0, but you can’t drive the car with the scanner connected. A bad sensor usually outputs some impossible value or no value, not zero. There are also no codes stored and no implausible warnings. The transmission looks okay at first glance. The ECU is also calculating a torque value. That leads me to think the problem is in the ECU itself, but I don’t want to jump to that conclusion without an actual MB Tech chiming in. Have you tried clearing the P061 code?

Since you swapped the cam position sensors and the DTC didn’t move, then the indication is correctly associated with the intake side. If you’re not having the hard starting and the rattling that go with cam adjuster failures, you may have a wiring harness or connector problem.

As you might know the car had water damage and I tried to replace most of the connectors and distributors under the carpet. Now I unplugged the connector to the sensor and turn the ignition to the second position and checked the voltage on the outside terminals of the connector which I got 12 V and then changed it to the middle terminal and the outside where I also got 12 v but when I moved the to the other side I got 0.4 volts. Is the middle wire going to the ECU and is it possible that not getting signal

I also replaced the blow off valve in the image below without the short thick spring because couldn’t find a place for it. This part is really making a difference.

Do you have wiring diagram for the camshaft sensor

Nope. I don’t have a complete wiring diagram. Maybe one of those WIS copies available on eBay would help. On electrical/electronics I can only help where I’ve been before. The P061 transmission codes are eligible for a waiver on emissions testing in Texas, and I’m a P034062 camshaft adjuster sufferer. You’re now in deeper than my knowledge goes.

And, yes, we’re all on the sidelines cheering you on with the resurrection of your submarine.

The engine is running and the connector is plugged in. The voltage on the first and second wires are 13.5 volts and the third wire which is the red was .01 volts.


https://photos.app.*******/hRb7ax3XH2ZZrEL39


and the second clip is the connector unplugged and the ignition is on the second position, the results were 12 volts for the first and second and the red one was 0 volts
the negative terminal of the multimeter is on the negative terminal of the battery

Do these findings mean anything

Which one of these three wires is the signal from the computer and what are the other two?

This may help someone p061b96 check the Cam Adjuster Magnet Solenoid sometimes this parts fail after 45 to 65 MPH
