P1338 Code Chevrolet – Glow Plug Cylinder 1 Offset Exceeded Learning Limit

Possible Causes

NOTE: The listed causes may not be a complete list of all potential issues and there may be other causes.

  • Perform the glow plug learning procedure
  • Faulty glow plug 1
  • Glow plug 1 circuit is open or shorted
  • Poor electrical connection in glow plug 1 circuit

What does this mean?

Technical Notes

If a glow plug has been replaced, perform a glow plug learning procedure using a scan tool.⚠

Description

The glow plug control module has not learned the glow plug offset values. If a glow plug has been replaced and glow plug learning has not been performed, or if the glow plug control module encounters an EEPROM error or data corruption, this diagnostic trouble code (DTC) will be set. The DTC will be set if the hot resistance of the glow plugs is outside a predetermined threshold.

How to Repair

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 engine maintenance warning light soon)

P1338 Code Volkswagen – Bank 1 Camshaft Position Sensor, Open Circuit or Short to Positive

Possible Causes

NOTE: The listed causes may not be a complete list of all potential problems and there may be other causes.

  • Faulty Camshaft Position (CMP) Sensor
  • Faulty Crankshaft Position Sensor
  • Camshaft Position Sensor Harness is Open or Shorted
  • Poor Electrical Connection in Camshaft Position Sensor Circuit
  • Faulty Engine Control Module (ECM)
  • Incorrect Engine Timing

What Does This Mean?

Technical Notes

Description

This error code is stored in the Engine Control Module (ECM) when the input signal from the Camshaft Position (CMP) Sensor is not within the operating range. There may be a timing issue between the Camshaft Position Sensor and the Crankshaft Position Sensor, and they should be tested with an oscilloscope.
This Diagnostic Trouble Code (DTC) can be caused by a faulty Camshaft Position Sensor, incorrect camshaft/crankshaft correlation, a fault in the Camshaft Position Sensor circuit, incorrect engine timing, and/or a faulty Engine Control Module. Additionally, any mechanical fault can also cause this DTC.

How to Fix

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)
