Concern: Turns off after 20-30 minutes, can't turn back on until hour+ later, P0335 crank no start all the time now after replacing sensor
DTC's: P0335 Crankshaft Position Sensor A Circuit
Modifications: CorkSport Stage II Short Ram Intake
ECU/Tuning Software: N/A
Tuner: N/A
Is the concern intermittent? it was, now it's permanent
Can you duplicate the concern? Yes
Recent Repairs: Passenger CV axle outer cv broke, P0340 camshaft position sensor a circuit
Correction: replaced passenger axle, replaced camshaft position sensor, checked wiring and ground near valve cover and harness.
Hey everyone, I've been trying to figure out this issue I've been having for the past week.
At first I would feel random rpm drops and hesitation randomly in all gears, on the street and highway. Eventually it felt like I lost fuel pressure as the car died on the highway after 30 minutes of driving. I was able to coast it to the shoulder and Freeway Service Patrol was able to tow me off the freeway to a designated CHP drop off point. Because it wouldn't turn back, I left it there for the night. The next day I was able to start it up again and drive another 20 minutes back to my house without any issues.
I checked the codes with Torque and the only thing I got at the time was P0340 (Camshaft Position Sensor "A" Circuit). Fine, I replaced the sensor, drove it around the block a few times and the code hasn't popped back up.
I leave for work an hour later and BAM! 20 minutes in and I feel the car getting sluggish on my way to work so I pull off the highway and made it to the next light before the car dies out again. Try cranking it and it does the same exact thing; no start. Waited an hour before I was able to start the car again and just went back home instead of risked getting stuck at work and trying to get a tow after midnight.
Scanned the car again and this time I'm getting P0335 (Crankshaft Position Sensor "A" Circuit). I bought a new sensor online and it came in Saturday.
Which leads me to today. I get under the passenger side, remove the bolt behind the sensor and install a timing kit bolt, manually turned the crankshaft pulley to the stop point of the timing tool, ensured it was at TDC, counted 20 teeth counter clockwise from the gap and lined up my new CKP sensor to it. Tried moving it up and down with no start still.
Now it just cranks and cranks, whether the car is cold or warmed, it doesn't turn on anymore at all. Now I'm instantly getting P0335 with KOEO, scanning after 4 seconds of cranking.
I've already tried putting the old/original sensor back on and it's still doing the same thing. I'm wondering if the wiring harness is damaged at this point so I'm starting to take continuity tests from the connector to up the harness near the alternator.
Pulling back the sleeve, I'm seeing 4 wires but only 3 on the connector. One wire is shielded and electrical taped to the B connected wire. I'm not sure what this is for, or if it's supposed to be like that. Can anyone confirm?
I'm getting continuity from connectors A and B from the plug to the wires directly behind it, but I may need to rewire C since there seems to be no continuity. Is C battery?
