P2580 Possible Causes

• Faulty turbocharger speed sensor
• Turbocharger speed sensor harness is open or shorted
• Poor electrical connection in turbocharger speed sensor circuit

How to Fix Code P2580

Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector pins.

Possible Symptoms

Illuminated engine light (or service engine soon warning light)

P2580 Meaning

The Powertrain Control Module (PCM) monitors the signal from the turbocharger speed sensor circuit. The PCM sets the OBDII code when the turbocharger speed sensor signal is outside factory specifications.

• Faulty turbocharger speed sensor
• Turbocharger speed sensor harness is open or shorted
• Poor electrical connection in turbocharger speed sensor circuit

How to Fix Code P2581

P2583 Possible Causes

• Faulty front distance range sensor
• Front distance sensor beam is open or short-circuited
• Front distance range sensor circuit poor electrical connection

How to Fix Code P2583

Check the “Possible Causes” listed above. Visually inspect the cable harness and related connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

Possible Symptoms

• Engine light on (or service engine soon warning light)
• Cruise control stops working

P2583 Meaning

The front distance sensor detects reflected light from a vehicle ahead by radiating laser forward and calculates a distance to the vehicle ahead and a relative speed. Based on the detected signal, the front distance sensor transmits the presence/absence of the vehicle ahead and the vehicle distance to the vehicle’s cruise control. When the vehicle’s cruise control loses communication with the front distance sensor, the cruise control requests the Engine Control Module (ECM) to set the OBDII code.

P2584 Possible Causes

• Fuel additive tank
• Faulty fuel additive sensor
• Faulty fuel additive control module
• Fuel additive control module harness is open or shorted
• Poor electrical connection in fuel additive control module circuit

How to Fix Code P2584

Check the “Possible Causes” listed above. Visually inspect the wiring harness and related connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

Possible Symptoms

Engine light on (or service engine soon warning light)

P2584 Meaning

The main purpose of the fuel additive control module is to calculate the required amount of fuel additive and control the injection timing into the fuel tank. It also stores diagnostic trouble codes (DTC) for the fuel additive system. In addition to the previously mentioned operation of the fuel additive system module, the instrument cluster will receive a command from the fuel additive system module to illuminate the malfunction indicator lamp (MIL) or powertrain control module (PCM) warning indicator if there is a problem with the additive system or if the fuel additive tank requires refilling. The PCM will set the OBDII code when the fuel additive control module requests the MIL to illuminate.

P2585 Possible Causes

• Fuel additive tank
• Faulty fuel additive sensor
• Faulty fuel additive control module
• Fuel additive control module harness is open or shorted
• Poor electrical connection in fuel additive control module circuit

How to Fix Code P2585

Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

Possible Symptoms

Illuminated engine light (or service engine soon warning light)

P2585 Meaning

The PCM will set the OBDII code when the fuel additive control module requests the warning light to turn on.

Symptoms

Symptoms of a P2586 code may include:

• Malfunction indicator lamp illuminated
• Poor performance
• Hesitation during acceleration
• Decreased fuel economy

Causes

Potential causes

for setting this code are as follows:

• Open in the TBCPS sensor signal circuit – most likely
• Short to voltage in the signal circuit to the TBCPS sensor
• Short to ground in the TBCPS sensor signal circuit
• Open in power or ground to the TBCPS sensor – most likely
• Failed TBCPS sensor – possible
• Failed PCM – unlikely

Diagnostic and Repair Procedures

A good starting point is always to check the technical service bulletins (TSBs) for your specific vehicle. Your issue may be a known problem with a known fix released by the manufacturer and can save you time and money when diagnosing.

Next, locate the TBCPS sensor on your specific vehicle. This sensor is usually directly screwed/bolted into the turbocharger housing. Once located, visually inspect the connector and wiring. Look for scrapes, rubbing, bare wires, burns, or melted plastic. Disconnect the connector and carefully inspect the terminals (the metal parts) inside the connector. See if they look burned or have a greenish tint indicating corrosion. Use electrical contact cleaner and a plastic-bristled brush if cleaning the terminals is necessary. Let it dry and apply electrical grease where the terminals make contact.

If you have a scan tool, clear the diagnostic codes from memory and see if the P2586 code returns. If it does not, the connections were likely your problem.

If the P2586 code returns, we will need to test the TBCPS sensor and its associated circuits. With the key off, disconnect the electrical connector from the TBCPS sensor. Connect a black wire from the digital voltmeter to the ground terminal at the TBCPS sensor wiring harness connector. Connect the red wire from the digital voltmeter to the power supply terminal at the TBCPS sensor wiring harness connector. Turn the key to the engine off position. Check the manufacturer’s specifications; the voltmeter should read 12 volts or 5 volts. If not, repair the open in the power or ground wiring or replace the PCM.

If the previous test is successful, we will need to test the signal wire. With the connector still disconnected, move the red voltmeter wire from the power wire terminal to the signal wire terminal. The voltmeter should now read 5 volts. If not, repair the open in the signal cable or replace the PCM.

If all previous tests are successful and you continue to get a P2586, this would most likely indicate a faulty TBCPS sensor, although a faulty PCM cannot be ruled out until the TBCPS sensor has been replaced. If in doubt, seek assistance from a qualified automotive diagnostician. PCMs must be programmed or calibrated to the vehicle to be installed correctly.

If you have a scan tool, clear the diagnostic codes from the memory and see if the P2587 code returns. If it doesn’t, the connections were likely your problem.

If the P2587 code returns, ensure you have good turbo boost pressure by testing with a mechanical gauge. Check your vehicle manufacturer’s specifications. If the boost pressure doesn’t meet specifications, determine the main issue with the low boost pressure (possible exhaust restrictions, wastegate problem, faulty turbocharger, intake leaks, etc.), clear the codes, and test again. If the P2587 is now gone, then the problem was mechanical.

If the P2587 code returns, we will need to test the TBCPS sensor and its associated circuits. With the key off, disconnect the electrical connector from the TBCPS sensor. Connect a black wire from the digital voltmeter to the ground terminal at the TBCPS sensor wiring harness connector. Connect the red wire from the digital voltmeter to the power supply terminal at the TBCPS sensor wiring harness connector. Turn the key to the engine off position. Check the manufacturer’s specifications; the voltmeter should read 12 volts or 5 volts. If not, repair the open in the power or ground wiring or replace the PCM.
