Codes: P0573, P0443, P0141, P0135, P0102, P0054, P0053, P0036, P0030. What do these codes mean?

Check for broken wires as these codes are unrelated.

No code tells you to replace a part , need to do diagnostic's for said code .

DW9 DTCS P0135, P0139, P0141, P0147, P0155, P0159 OR P0161: CHECK FOR A SOURCE OF POTENTIAL HO2S CONTAMINATION

• Investigate the following items as potential sources of HO2S contamination:
  • use of unapproved silicon sealers
  • fuel contaminated by silicon additives
  • excessive oil consumption
  • glycol leaking internally in the engine
  • lead-contaminated fuel
  • short drive cycles in cold weather
  • use of unapproved cleaning agents

Is a concern present?
Yes No REPAIR the source of the contamination.

CHANGE the engine oil and oil filter.

RESET the keep alive memory (KAM). REFER to Section 2, Resetting The Keep Alive Memory (KAM) .

REPEAT the self-test. GO to DW10 .

DTC P0014: Exhaust Camshaft Position (CMP) System Performance

What is the trouble code or are you just throwing parts at it to see how much money you can waste?

It looks like you have two bad O2 sensors an a bad mass air flow sensor . Is your vehicle a 4 cylinder or 6 0r 8 cylinder ? Bank 1 sensor 1 an bank 1 sensor 2 heater circuits . plus you have a EVAP. emission purge control circuit problem ! I would go on you tube an enter your trouble codes to see videos on testing

Yes there is something in common . Check the fuse # 79 10amp in the underhood fuse box . For O2 sensor , heater power .
The PCM commands the heater ON or OFF to maintain a specific HO2S operating temperature range. The PCM monitors the voltage on the HO2S heater low control circuit for heater fault diagnosis. If the PCM detects that the HO2S heater low control circuit voltage is not within a specified range, DTC P0030 sets for HO2S 1, or DTC P0036 sets for HO2S 2.
So this is not in spec. an it set the other codes !
If the PCM detects that the heater current or the heater calculated resistance is not within an expected range, DTC P0135 sets for HO2S 1
If the PCM detects that the heater current or the heater calculated resistance is not within an expected range, DTC P0141 sets for HO2S 2.

Check your fuse and replace any that are burnt out. It is possible that it your heater on your O2 sensor shorted that it blew the fuse.

Hi,

Code explanations as follows:

P0030 = HO2S Heater Control Circuit (Bank 1 Sensor 1)
P0053 = HO2S Heater Resistance (Bank 1, Sensor 1)
P0054 = HO2S Heater Resistance (Bank 1, Sensor 2)
P0134 = 02 Sensor Circuit No Activity Detected (Bank 1, Sensor 1)
P0302 = Cylinder 2 Misfire Detected


Cheers,

There is a fault with the inbuilt heater in the oxygen sensor, before the catalytic converter, on the exhaust pipe the same side of the engine as cylinder 1. The oxygen sensor has four wires within the cable sheath to the top of it. Two of the wires will share the same color. These wires supply power to an internal heating element wire within the sensor. Follow the cable from the oxygen sensor to the connector, you can do a lot testing here. Check the resistance between the two 'same coloured ' wires. The resistance is low, somewhere between 1 and 10 ohms. If there is no continuity (infinite resistance) then this is the fault and the sensor needs to be replaced. The codes: P0030 the oxygen sensor heater relay is at fault P0053 Oxygen heater resistance error P0135 Sensor 1 bank 1 error You are looking at replacement. A further confirmation take the connection from sensor 1 bank 1 and swap it with the sensor 1 bank 2 on the other side of the engine. The codes should 'transfer' and show P0036; P0059 and P0141.

May be errant codes from losing power, erase them and see if they come back - [ I'm betting they won't.]
