Order of inspection
P0373 Timing Reference High Resolution Signal A Intermittent/Erratic Pulses Medium
The P0373 code means the signal on high resolution timing reference signal A appears and disappears or changes shape, which usually points to a bad contact or a faulty sensor. The computer uses this signal to work out engine position precisely. The engine usually keeps running on the low resolution signal alone, but less smoothly.
