FIRE
PFP:00000
On Board Diagnosis LogicUBS00QGZ
When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the crank-
shaft position (CKP) sensor (POS) signal to vary, ECM can determine that a misfire is occurring.
The misfire detection logic consists of the following two conditions.
1. One Trip Detection Logic (Three Way Catalyst Damage)
On the 1st trip that a misfire condition occurs that can damage the three way catalyst (TWC) due to over-
heating, the MIL will blink.
When a misfire condition occurs, the ECM monitors the CKP sensor (POS) signal every 200 engine revo-
lutions for a change.
When the misfire condition decreases to a level that will not damage the TWC, the MIL will turn off.
If another misfire condition occurs that can damage the TWC on a second trip, the MIL will blink.
When the misfire condition decreases to a level that will not damage the TWC, the MIL will remain on.
If another misfire condition occurs that can damage the TWC, the MIL will begin to blink again.
2. Two Trip Detection Logic (Exhaust quality deterioration)
For misfire conditions that will not damage the TWC (but will affect vehicle emissions), the MIL will only
light when the misfire is detected on a second trip. During this condition, the ECM monitors the CKP sen-
sor signal every 1,000 engine revolutions.
A misfire malfunction can be detected on any one cylinder or on multiple cylinders.

3. Press support bearing assembly off slide joint assembly using a
suitable tool.
4. Remove dust shield.
Damper

Remove damper bands, then remove damper from shaft.
INSPECTION AFTER DISASSEMBLY
Shaft
Replace shaft if there is bending, cracking, or other damage.
Joint Sub-Assembly

Make sure there is no rough rotation or unusual axial looseness.

Make sure there is no foreign material inside joint sub-assembly.

Check joint sub-assembly for compression scars, cracks or fractures.
CAUTION:
If there are any irregular conditions of joint sub-assembly components, replace the entire joint sub-
assembly.
Slide Joint Housing and Spider Assembly
Make sure there are no compression scars, cracks, fractures or unusual wear of housing or spider roller con-
tact surface.
CAUTION:
If there are any irregular conditions of the slide joint housing and spider assembly components,
replace them as a set.
Support Bearing
Make sure wheel bearing rolls freely and is free from noise, cracks, pitting or wear.
Support Bearing Bracket
Check for bending, cracks, or damage.
Damper
Check damper for cracks or wear. Replace as necessary.
ASSEMBLY
Transaxle Side
1. Install new boot and new small boot band on shaft.
CAUTION:

Do not reuse boot or boot band.

Cover drive shaft serration with tape to prevent damage
to boot during installation.
2. Remove protective tape wound around serrated part of shaft.
