Perez had been working shut behind Ferrari’s Carlos Sainz within the early levels of the race, and appeared poised to launch a problem for what would have been third spot when his engine misplaced energy.
The issue was traced to a sensor fault triggering an computerized shutdown of some methods, and the crew’s engineers needed to reprogramme issues to maintain him going.
Regardless of the continued lack of energy, Perez nonetheless managed to shadow Sainz dwelling and end fourth, having tried a late cost on medium tyres.
However after the race, Pink Bull crew boss Christian Horner confessed that the sensor downside was such that it was questionable whether or not or not the Mexican was going to make it to the chequered flag.
“It was very shut,” mentioned Horner in regards to the dangers of a DNF. “We needed to transfer the sensors round to deal with the difficulty. In order that’s one thing we’ll work carefully with HRC [Honda’s engine division] on to attempt to perceive and clearly ensure that it does not occur sooner or later.”
Horner defined that the issue with the sensor was on the inner combustion engine, and was costing Perez a good chunk of lap time.

Nevertheless it notably damage his prime pace, which meant that he couldn’t fairly get the end-of-straight benefit he wanted over Sainz to launch a correct problem within the closing levels.
“He had a problem with a sensor on one of many cylinders,” added Horner. “The blokes managed to maneuver the sensors round, however he was down most likely 20 kilowatts in energy because of this.
“Even with the benefit of the brand new tyre he had, he was most likely half a second off what the automotive was able to in straight line pace. And I feel with out that he would have most likely even been P2.”
Whereas Perez’s sensor downside is the most recent in a string of reliability issues which have hit Pink Bull this 12 months, Horner doesn’t assume the crew has an excessive amount of to fret on that entrance.
“I do not assume the automotive is especially fragile,” he mentioned. “I feel there’s simply been niggly issues that you’d have usually seen in pre-season testing however have solely reared their head as we have into the season,” he mentioned.
“That is been irritating. However we’re working carefully with HRC and so they’re giving us nice assist. So I feel we’ll get these ironed out.”
