I have thrown 3 trouble codes the other day. all at once, check engine light came on.

truck has 4" mbrp exhaust and hypertech, and kn, chip was set to level 3 when this occured.

p0336
p0602
p1693

I know 2 of those codes are crank sensor codes. Question is im leaving town this afternoon to go to the delta, and towing the ski boat. Do any of these codes warrant me not using the truck?

i cleared them and it tripped them again.

last time i got the last 2 codes i drove it for a few weeks before replacing the crank sensor.

 

P0336 (M) Crankshaft Position (CKP) Sensor
Signal. Problem with voltage signal from CKP.

P0602 (M) ECM Fueling Calibration Error ECM Internal fault condition detected.

P1693 (M) DTC Detected in PCM/ECM or DTC Detected in ECM.
A Companion DTC was set in both the ECM and PCM.

I wonder what's causing the problem?

 

r u implying its the hypertech chip?

 

Nope, I'm wonderin' about the wiring to the Crank position sensor.
I can't even guess about the ECM fuel problem but if you unplugged your programmer, reset the DTC's and the ECM fuel problem didn't come back, I'd be ringin' them Hypertech boys telephone.
I read that a Crank Position sensor scratched up on the end is a real problem.
Does that programmer burn the chip?
