Vehicle:
2001 Honda CRV 4 Wheel Drive OBD2b

Components:
Swapped B20Z2 with JDM B20B using US intake/exhaust/MAP/MAF/IACV/TPS (TPS broke, installed a new 1 non-calibrated). Downpipe/exhaust manifold connected (not the cat/remaining exhaust/both O2 sensors). Attempted CKF Bypass using .:FFS TechNet : CKF Bypass Trick :. guide and upon cylinder 2/3 no fire, wired back to OEM settings/pinouts.

Codes:
p0122 (Throttle Position Sensor/Switch A Circuit Low Input), p0135 (Oxygen O2 Sensor Heater Circuit Malfunction [Bank1, Sensor1]), p0141 (Oxygen O2 Sensor Heater Circuit Malfunction [Bank1, Sensor2]), and p1337 (Crankshaft Position Sensor 2 No Signal)

Problem:
Cylinder 2 and Cylinder 3 have no spark.

Attempted Diagnosis:
New dizzy, wires, and plugs = no difference.
(Looks like there's spark at dizzy, not at wire ends [Have used 4 sets of wires])

FYI:
Bypass uses C22 (CKFP), C29 (CYPP), C30 (CYPM), and C31 (CKFM). Compression is 190 on all cylinders.

Question 1) Will any of these codes "de-rate/detune" the engine to the point of creating no spark on 2 cylinders?

Question 2) Will a faulty attempt at the bypass, using ONLY those four wires, cause the no spark?

Question 3) What is the next step in diagnosing?

 

Check ur bypass work
Fix the codes
Then try it again
