DTC P0133 DTC P0153 | HO2S (Front, RH) slow response HO2S (Front, LH) slow response
--- | ---
DETECTION CONDITION | • PCM monitors lean-to-rich response time and rich-to-lean response time of the sensor. PCM calculates the average response time from lean-to-rich, and from rich-to-lean when monitoring conditions are met. If the following condition, PCM determines that circuit has malfunction.

  - The average value of lean-to-rich/rich-to-lean response time is more than the threshold value.

MONITORING CONDITIONS

  - Drive mode 3
  - Following conditions are met:

  • Calculation load 26.6- 57.8% (at engine speed.2,000 rpm)
  • Vehicle speed is above 69.6 km/h {43.2 mph}
  • Engine speed 1,410- 2,500 rpm
  • Engine coolant temperature is above -10 °C {14 °F}
  • Front HO2S signal inversion cycles is above 7 cycles

Diagnostic support note
• This is an intermittent monitor. (HO2S)
• The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
• PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
• DIAGNOSTIC MONITORING TEST RESULTS is available.
• FREEZE FRAME DATA is available.
• DTC is stored in the PCM memory.
POSSIBLE CAUSE | • Front HO2S deterioration • Front HO2S heater malfunction • Pressure regulator malfunction • Fuel pump malfunction • Fuel filter clogged or restricted
• Fuel leakage on fuel line from fuel distribution pipe and fuel pump
• Fuel return hose clogged
• Leakage exhaust system
• Purge solenoid valve malfunction
• Purge solenoid hoses improper connection
• Insufficient compression
• Engine malfunction

No | Go to troubleshooting procedures for DTC on FREEZE FRAME DATA. (See DTC TABLE [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed)).)
5 | VERIFY CURRENT INPUT SIGNAL STATUS • Warm up engine. • Access O2S11 for P0133 or O2S21 for P0153 PID using WDS or equivalent. • Check PID under following accelerator pedal conditions (in PARK). • Is PID reading normal?

- Above 0.55 V when suddenly depress accelerator pedal (rich condition).

- Below 0.55 V just after release of accelerator pedal (lean condition).

Yes
Go to step 8.
No | Go to next step.
6 | INSPECT INSTALLATION OF FRONT HO2S • Check if front HO2S is loosely installed. • Is sensor installed securely? | Yes | Go to next step.
No | Retighten sensor, then go to Step 14.
7 | INSPECT GAS LEAKAGE FROM EXHAUST SYSTEM • Visually check if any gas leakage is found between exhaust manifold and front HO2S. • Is there any gas leakage? | Yes | Repair or replace any faulty exhaust parts, then go to Step 14.
No | Replace sensor, then go to Step 14.
8 | INSPECT LONG TERM FUEL TRIM • Access following PIDs

  - For P0133: LONGFT1
  - For P0153: LONGFT2

• Compare it with FREEZE FRAME DATA (FFD) recorded at Step 1.
• Is it below FFD value?
Yes
Engine is driven under rich condition. Go to next step.
No | Engine is driven under lean condition. Go to step 10.
9 | INSPECT FUEL LINE PRESSURE (Excessive fuel line pressure) • Turn the ignition switch off. • Inspect fuel line pressure while engine running. (See FUEL LINE PRESSURE INSPECTION [AJ].) • Is fuel line pressure normal? | Yes | Go to next step.
No | Inspect fuel pump maximum pressure and fuel return pipe for clogged. (See FUEL PUMP UNIT INSPECTION [AJ].) • If any problem is found, repair or replace suspected parts. • If all items above are normal, replace pressure regulator. Then go to Step 14.
10 | INSPECT FUEL LINE PRESSURE (Low fuel line pressure) • Turn the ignition switch off. • Inspect fuel line pressure while engine running. (See FUEL LINE PRESSURE INSPECTION [AJ].) • Is fuel line pressure normal? | Yes | Go to step 14.
No | Go to next step.
11 | INSPECT FUEL PUMP MAXIMUM PRESSURE • Perform fuel pump maximum pressure test. (See FUEL PUMP UNIT INSPECTION [AJ].) • Is fuel pump maximum pressure normal? | Yes | Go to next step.
No | Inspect fuel pump circuit for open or poor connection. • Repair or replace suspected circuit. • If circuit is normal, replace fuel pump. Then go to Step 14.
12 | INSPECT FUEL LINE FROM FUEL PUMP TO FUEL DELIVERY PIPE • Visually inspect fuel line for any leakage. • Is any fuel leakage found? | Yes | Replace suspected fuel line, then go to Step 14.
No | Inspect fuel filters for follows: • Restriction or clogging at fuel filter (high-pressure side) • Foreign materials or stain inside fuel filter (low-pressure side) Perform following actions as result. • If restriction or clogging is found at fuel filter (high-pressure side), replace fuel filter.
• If foreign materials or stain is found inside fuel filter (low-pressure side), clean of fuel tank and filter.
• If all items above are normal, replace pressure regulator.
Then go to Step 14.
13 | INSPECT SEALING OF ENGINE COOLANT PASSAGE

  Warning

  • Removing radiator cap when radiator is hot is dangerous. Scalding coolant and steam may shoot out and cause serious injury.
  • When removing radiator cap, wrap a thick cloth around and turn it slowly.

• Remove radiator cap.
• Implement procedure to bleed air from engine coolant, then run engine at idle.
• Is there any small bubble, which makes engine coolant white at filling opening?

  Note

  • Large bubbles are normal since they are remaining air coming out from engine coolant passage.

Yes
Air gets in from poor sealing on head gasket or other areas between combustion chamber and engine coolant passage.
Repair or replace faulty parts, then go to next step.
No | Go to next step.
14 | VERIFY TROUBLESHOOTING OF DTC P0133 or P0153 COMPLETED • Make sure to reconnect all disconnected connectors. • Turn the ignition switch to ON (Engine OFF). • Clear DTC from memory using WDS or equivalent. • Start engine.

• Access DIAGNOSTIC MONITORING TEST RESULTS.
• Verify following TEST # values:
(See Diagnostic monitoring test results access procedure.)

  - For P0133:

  10:01:05 (HO2S (RF) rich-to-lean response time)
  10:01:06 (HO2S (RF) lean-to-rich response time)
