S63R, S63T, or XB2H engine.
SITUATION
In certain situations, when the crankshaft position signal is lost while driving, the malfunction indicator
lamp (MIL) and an engine malfunction check control message (CCM #29) may be displayed.
The engine may run roughly or with reduced power.
The following faults may be stored in the digital motor electronics (DME) fault memory:
Fault code:
Control module:
160001
DME
Or:
160020
DME
In conjunction with:
11A002
DME
May also be stored:
180001
DME
180101
DME
Fault code text:
Crankshaft sensor, signal: missing
Crankshaft sensor, signal: implausible
Fuel high pressure, plausibility: Pressure too low
Catalytic Converter: efficiency below threshold
Catalytic Converter 2: efficiency below threshold
CAUSE
The loss of an accurate crankshaft angle value while driving may subsequently damage the catalytic
converter.
2
CORRECTION
Evaluate the fault pattern and environmental details to determine the necessary repairs.
PROCEDURE
When fault code 160001 or 160020 and 11A002 are stored:
1. Evaluate the environmental conditions of 160001 or 160020
a. If the engine speed is greater than 1000 rpm
Continue to step 2
b. If the engine speed is 1000 rpm or less
Continue diagnostics using ISTA
2. Evaluate the environmental conditions of 180001, 180101, and 11A002
a. If 11A002 was not stored in conjunction with 180001 or 180101
Continue to step 3
b. If 180001 or 180101 was stored more than 620 miles after 11A002 was set
Continue to step 3
c. If 180001 or 180101 was stored under 620 miles after 11A002 was set
Replace the catalytic converter
Continue to step 5
3. Check the crankshaft sensor electrical circuits and inspect for damage
a. If a fault is identified in the crankshaft sensor circuit
Repair the identified fault
Continue to step 4
b. If no faults are found
Replace the crankshaft sensor
Continue to step 4
4. Remove the oxygen sensors or the exhaust clamp to inspect the catalytic converter monolith
a. If no damaged is observed
Continue to step 5
b. If damage is present
Replace the catalytic converter
Continue to step 5
5. Program the vehicle with ISTA 4.16.1x (released early March 2019) or higher to the
appropriate I level shown below:
